The field of Pharmaceutical organic chemistry has long presented a special problem for pharma chemists. Because of its enormous information content and variety, it is not well taught to chemistry undergraduate or graduate students, even in simplified form. There is simply too much material for the time available and yet, the chemistry of pharmaceutical compounds and methods for their synthesis form the bedrock of modern medicinal chemical and pharmaceutical research. It is important for medicinal chemists to be broadly knowledgeable across a wide swath of Pharmaceutical organic chemistry. Those who specialize narrowly do so at their own peril. So there is a need for high-quality, up-to date, and authoritative books on pharma chemistry that are helpful for the undergraduate students and also the advanced student. This book, a form of lecture note written concisely and with great skill that will be tremendously useful and helpful to pharma undergraduate students.
