The Chemistry of Longifolene and Its Derivatives

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
