The second book by Nicolaou has made a good impression to me. I use it for historical research for presentations of Natural Products Chemistry. The author Describes the Milestones of Discovery and Synthetic Approaches for many important natural products. Of course, most of the book is based on Nicolaou own work, but nonetheless, this is understandable, Regarding his field of work.
Good literature, Should be in every organic chemists bookshelf.
