Dedication

My First & Best Teacher - Beloved Mother

Gave me not only Respiration but also Inspiration

Shrimathi. V. KAMUTHAI

The inspirational words of my mother ringing in my ears are…….

“The two most important days in your life are the day you are born and the day you find out why you are born. In your life either write something worth reading or do something worth writing. You should dedicate yourself to your profession and do your best that should answer why you are born.”

Whatever the mind of man can conceive and believe, it can achieve. Challenges are what makes life interesting and overcoming them is what makes life meaningful. In order to succeed in your life, your desire for success should be greater than your fear of failure. It does not matter how slowly you go as long as you do not stop.

We become what we think about; hence your thoughts should always be of high-quality. Definiteness of purpose is the starting point of all achievement. If you believe you can do it you are halfway there. Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it. It will give you the required strength. “Nothing is Impossible in the world, because the word impossible itself says, I’m possible!”

When everything seems to be going against you, remember that the aircraft takes off against the wind, not with it. That is why it is reaching the desired destination. If you compromise for others, you cannot reach your destination, instead you will reach others destination.

Life shrinks or expands in proportion to one’s courage. Limitations live only in our minds. But if we use our imaginations, our possibilities become limitless. Hence you have enough opportunities in the world if you have courage. Do what you can, where you are, with what you have. You should have a dream in your life and to achieve it if you have good idea and clear plan with full devotion, it will fetch you sure success even if the God says impossible. Because the hard work has its own power, it will never fail. You should not be a product of your circumstances. You should be a product of your decisions.

As the students entering graduate course, understanding of Pharmaceutical organic chemistry is always

been a difficult task especially the various chemical reactions with their mechanisms of different kind of

organic compounds. Hence my efforts have been devoted to authoring a book by equipping with the

challenging requirements of the subject for the new generations of the teachers all over India and is easy to

read for students who are not necessarily of Pharmacy program, but mainly for the students of first time

reading organic reactions, their mechanisms and their applications in science, Pharmacy and medicine.

Methodical description of each chapter, enriching chemical and pharmaceutical background of the

medicinally important organic compounds, proceeding each group of organic compounds in a systematic

way in easy-to-understand style in the larger interest of the students without any difficulty and making the

reader acquainted thoroughly with chemistry of organic compounds is the unique feature of this book.

In preparing this text book, I have tried to enrich the importance of organic compounds in medicine and

pharmacy, so that the anticipated audience of this book will feel the importance of organic compounds

and made the book a comprehensive. The students of Pharmacy graduates of our country faced with the

scarcity of books to serve their needs. Few of the authors dealt well about the basics of organic chemistry,

but the reactions of organic compounds are not presented in a easy to understand manner which students

felt difficult to learn. Some of the books of organic chemistry fail to give the chemical structures for all

reactions, hence the students are unable to understand the reactions clearly. Hence the content of this

book is made as a humble attempt to cater the needs of academicians belonging to all Indian Universities by

incorporating the chemical structure of all reactions and enriching basic principles of each organic class of

compounds.

The book has covered the entire Pharmaceutical organic chemistry, starting from origin of organic

chemistry to advanced topics like stereochemistry and heterocyclic compounds and it is divided into 31

chapters. Chapter 1 to 7 deals with the basics of the organic chemistry, wherein the fundamentals like

origin and development of organic chemistry, structure of organic molecules and their related properties

are described. Classification and nomenclature of organic compounds and general terms used are also

presented in a systematic way, which is easy to understood and able to reproduce well in examinations.

Chapter 8 to 25 deals with Aliphatic and Aromatic compounds which are further divided into different

chapters and each chapter is dealt with Introduction, Importance of each class of compounds, Nomenclature,

General methods of preparation, General physical and chemical properties and Pharmaceutically important

organic compounds of each chapter are described in a easy to understand manner. Summary of methods

of preparation and chemical reactions in a flow chart manner presented is unique and helps student to

remember for exam which is the first of its kind.

Chapter 26 to 28 , Isomerism and detailed description of optical and geometrical isomerism is presented

in a simplified manner.

Chapter 29 to 30, Heterocyclic rings of various types and their utility in pharmaceutical chemistry is

described well. The medicinal compounds derived from each heterocycles also exemplified which makes

the reader inspiring.

In Chapter 31, Important reactions and reagents used in organic chemistry and some of the special

reactions are described with their mechanism and applications in Pharmaceutical organic chemistry.

To inspire the readers and make them attracted, interesting facts about great scientists and Organic

compounds and their discovery etc are given under each chapters.

Preface

Contents ix

In order to help students to remember well and reproduce well in exams, the style and presentation are

followed simple and similar pattern in all chapters. We have also used some special abbreviations like

“CAD” (which helps to remember cold Alkaline dilute).

To help the students to learn and magnetize the attention we have used color in equations and diagrams.

We have done it this thoughtfully and purposefully and not just to make the book attractive. These small

inputs helps a lot for the fresher’s who enter into degree program.

We hope that this special volume will be a good source of information and reference for not only to

graduates and post-graduate students but also for basic and applied researchers in this field. Moreover it

will also be of interest to a wide range of scientists who are involving in the Pharmaceutical organic

chemistry related research. I welcome suggestions and constructive criticism from all corners of scientific

community.

IntroductionIntroductionIntroductionIntroductionIntroduction

In early days, scientists named the compounds based on historic background. For example, “wood spirit” was named so because it was obtained from distillation of wood. Later it was named as methanol based on Greek words (methu = wine and hale = wood). Similarly, the name “acetic acid” was derived from vinegar (Latin; acetum = vinegar), because the acetic acid is the major constituent of vinegar. These are called as common names or trivial names. As the number of compounds were discovered more, naming by history becomes difficult. Hence systematic naming becomes important. The systematization of names was carried out by the International congress of leading chemistry held in Geneva, 1892. Rational system of nomenclature was formed and it is called as Geneva system of nomenclature. Slight revision and improvements were carried out time to time. One such being held at Liege (Belgium) 1930 by International Union of Chemistry and it is called as IUC system of nomenclature. The IUC was later modified by the International Union of Pure and Applied Chemistry in 1958 and it is called as IUPAC system of nomenclature. To name the organic compound according to IUPAC nomenclature a set of rules were framed and all the compounds are named accordingly. However, even today some of the common names are used for organic compounds. Hence the chemists should also be aware of the common names apart from IUPAC nomenclature. Non-systemic nomenclature of organic compounds like common name, trivial name etc are described in individual chapters.

IUPAC nomenclature is been used now a days to name organic compounds. However, some of the simple compounds are named by trivial names. Earlier names have been continued even today but complex organic compound can be given using IUPAC nomenclature only. Various rules are followed for naming compounds by IUPAC system: Rule 1: Longest chain rule: “In the given organic compound longest possible chain of carbon atoms is selected and the compound is named as a derivative of this alkane.” For example, the compound given below have five carbons in horizontal line and six carbons in the longest chain hence we should select it as a hexane derivative only.

Rule 2: Lowest number for substituents rule: After selecting the longest chain, the numbering should be given from one end to the other end. While giving the number, the substituents should be given lowest possible number. For example, the compound given below is named in two ways.

In first case, naming 4,7-dimethyl octane is not correct because 2,5-di methyl octane have lowest numbers for the substituents. If different alkyl groups are in equivalent positions in relation to the end of the chain, preference is given to the end where the radical has fewer carbon atoms (methyl, ethyl, etc ). In the following example, the first case of naming is correct because methyl group is given preference over ethyl group.
