 Title    Alkaloids, IX* Some Aspects of the Chemistry of C atliar anthine  
 Abstract    Vinblastine and Vincristine are binary indole-indoline alkaloids occurring in traces in the leaves of Vinca rosea. They are among the most powerful chemotherapeutic agents available to man for the treatment of a variety of cancers. Their high cost and complexity of structure has attracted the attention of many eminent chemists towards their synthesis. The first synthesis of both these anta'-tumour alkaloids was reported by us last year [7] starting from two major alkaloids, catharanthine and vindo-line, which co-occur in the same plant. Some aspects of the chemistry of catharanthine are now presented including a novel one-step de-carbomethoxylation reaction with H2S in glacial acetic acid and a reversible isomerization of catharanthine with sodium borohydride. A study of the life-time of catharanthine in hot glacial acetic acid substantiates the earlier work of the Anglo-French group on the biosynthesis of indole alkaloids.
