In the last decade, the organic chemist’s approach to Natural Product Chemistry has undergone a considerable change. It is now apparent that the structures of the majority of natural products can be determined absolutely and in a surprisingly short time by the method of X-ray crystallography. This method is however expensive, and at present it is not feasible to determine the structures of many natural products, particularly simple ones, by this method. Even so, the organic chemist is now conscious that the expenditure of several years on the determination of a structure of a natural product is no longer justified. Fortunately recent developments in various spectroscopic methods now enable the organic chemist to solve structures much more efficiently than in the past.
