This book reveals the logic behind the described methods and discuss the mechanisms. I never expected I would want to own another protection/deprotection reference book in addition to Greene's "Protective groups in organic synthesis" and I was wrong. Kocienski managed to present broad, comprehensive overview of a "boring but necessary" information as a most enjoyable and thought-provoking reading. The book is filled with carefully selected pieces from total syntheses, often illustrating formidable problems solved in a beautiful way. The book does not reference every single known methods as Greene's does, but is extraordinary informative. I believe the intellectual values of both books are comparable. If you are facing a problem (as usual :) or are designing a complex synthesis, I would suggest to read Kocienski's book first and then supplement it from Greene's. Works for me. If you enjoy the Synthesis, you will love this book.
