Chapter 2. Elucidation of Structural Formula, Configuration, and Conformation of Alkaloids by X-Ray Diffraction... 

Sophisticated physical techniques have had a major impact on alkaloid research, particularly on the determination of novel structures. Progress in this area will be reviewed periodically, and the chapter on Elucidation of Structural Formula, Configuration, and Conformation of Alkaloids by X-Ray Diffraction is the first of a series of such reviews. Attention is given to chemical methodology, found to be most valuable in alkaloid synthesis, presented here in the chapter on Application of Enamide Photocyclization in Alkaloid Synthesis. Of a more traditional nature is the presentation of alkaloid classes, which have not been reviewed for many years and where considerable new material has accumulated. Hence, two chapters, namely, The Imidazole Alkaloids, last reviewed in Vol. Ill (1953) and Ipecac Alkaloids and (3-Carboline Congeners, reviewed in Vol. XIII (1971), are included.
