Abstract

With the introduction of modern spectroscopic methods of structure elucidation, the role of chemical reactions in the structure determination of natural products has become minimal. Increasingly, complex organic structures are being elucidated by X-ray crystallography, a technique which essentially by-passes the organic chemist! These advances constitute a water-shed in the development of chemistry of natural products and have enabled the chemists to direct efforts to aspects of natural product chemistry considered unassailable till recently. However, on the other hand, the classical approach involving chemical transformations has, in the past, generated a fund of interesting and unexpected results, often of fundamental importance. This is because many complex natural products have such built-in stereo-electronic features that their chemical transformations, not too infrequently, lead to totally unanticipated results *. It is suggested that chemical transformations of easily available, novel, complex organic molecules deserve to be investigated so that the excitement of the unexpected is not completely lost! The structure of longifolene, a sesquiterpene mono-olefin, was established in 1953, but still, twentyfive years later, continues to attract attention as an unusual substrate for transformations which generate much exciting chemistry. The present article has been written to high-light this aspect of longifolene chemistry, as an example of another facet of natural products chemistry.
