Preface

前言

Welcome to organic chemistry course.

Earlier, we have learned general chemistry. Chemistry is the study of the nature,

properties, and composition of matter, and how these undergo changes. Organic chemistry,

in short, is the study of organic compounds. Some organic compounds have been known

since ancient antiquity. Prehistoric peoples were familiar with sugar, with the fermentation

of the grape and the production of wine, and with the souring of wine under the agency of

acetobacter to produce vinegar. Vegetable oils and animal fats, and the process of making soap

from these substances, have been known for centuries. Since all organic compounds known

at the beginning of the 19th century had been isolated as products of the life process, namely,

all organic compounds were derived from the products of the life process, the belief was

current for a time that organic compound could arise only through operation of a “vital force”

inherent in living cells. Organic compound, the name its self, implies organism. However,

repeated demonstration that compounds identical in all respects with those obtained from

plants and animals could be prepared from mineral materials. Now, most natural products

known have been prepared synthetically, and pure synthetic organic compounds exceed by

far those found in nature. Organic chemicals are put to many varied uses. They are worn

as clothes, eaten as foods, and used as fuels. They include “wonder” drugs, vitamins, and

hormones as well as deadly poisons.

The study of organic compounds is important to anyone who endeavors to understand

the complex activities of living systems and the material world. The vast majority of living

materials are organic compounds such as saccharide, lipid, protein and nucleic acid and so

on. The metabolic process in humans is a series of organic chemical reactions. To understand

clearly these reactions in living organisms at the molecular level, the knowledge of organic

chemistry is essential. Moreover, organic chemistry is also the foundation of biochemistry,

pharmacology, and other subjects related to medicine.

In the text, after the introduction of various molecular framework species (alkanes,

alkenes, arenes), the aliphatic and aromatic compounds are treated together even though their

differences in chemical properties.

The study of organic chemistry by means of the various functional groups continues to

be the simplest, most natural, and most effective way of easing the burdens of the learning

process. Therefore, the text is organized according to functional groups. Organic chemistry

uses functional groups as the framework within which chemical reactions are discussed. Thus,

the emphasis is placed on the reactions that different functional groups undergo, not on the

reactions that prepare them. Moreover, similar reactions are grouped together so that parallels

can be emphasized. Exercises in the text appear both within and at the end of chapters. Those

within the chapters are intended to test comprehension of specific points made in that section

of the text. Exercises at the ends of chapters are more comprehensive and include both drill

and thought questions.

With the joint efforts of some organic chemistry teachers who have taught international

students for many years, the first edition of organic chemistry textbook finally comes into use.

It follows closely the organic chemistry syllabus of clinical medical education for international

students. This textbook has been absorbed feedback from teachers and students actually

teaching and learning organic chemistry. Today’s students rely more heavily on visual

imagery to learn than ever before. We have therefore written the text that uses less written

narrative and more diagrams, equations, tables, and examples to introduce and reinforce the

major concepts and themes of organic chemistry. The text is arranged into twelve chapters

that cover introduction of organic chemistry (chapter 1), hydrocarbons (chapter 2-3), organic

compounds containing oxygen, sulfur and nitrogen (chapter 4-7), optical isomerism (chapter

8), and important life substances ——carbohydrates, lipids, proteins and nucleic acids (chapter

9-12).

Although the book has been carefully modified many times, it is still hard to avoid

mistakes and deficiencies. I earnestly hope broad teachers and students put forward valuable

opinion. Finally, I would like to express my thanks to all cooperators to pay hard work,

especially my colleagues, professor Sun Yanhua and professor Shen Wanqiu, for their

contributions and supports. I would also like to thank the editor staff of Tsinghua university

publishing house for publishing the book's efforts.
