Summary

This book presents key aspects of organic synthesis – stereochemistry, functional group transformations, bond formation, synthesis planning, mechanisms, and spectroscopy – and a guide to literature searching in a reader-friendly manner.

•    Helps students understand the skills and basics they need to move from introductory to graduate organic chemistry classes
•    Balances synthetic and physical organic chemistry in a way accessible to students
•    Features extensive end-of-chapter problems
•    Updates include new examples and discussion of online resources now common for literature searches
•    Adds sections on protecting groups and green chemistry along with a rewritten chapter surveying organic spectroscopy
