Abstract: | (+)-9-Demethylpsychotrine (I) has been synthesized from ethyl cincholoiponate (+)-III] and 3-benzyloxy-4-methoxyphenacyl bromide by the “cincholoipon-incorporating method” through the intermediates IV–VI and VIII–XVII. Identity of synthetic (+)-I with desmethylpsychotrine unequivocally established the structure of the alkaloid. |
