- 中文摘要: Two products, 3-hydroxy-9,10-dimethoxyprotoberberine and 3,9-dihydroxy-10-methoxyprotoberberine in addition to those reported, 2-hydroxy-9,10-dimethoxyprotoberberine and 2,9-dihydroxy-10-methoxyprotoberberine, were identified from cleavage of canadine with sodium in liquid ammonia. This reaction indicates regioselectivity rather than the reported regiospecificity by cleavage mainly at a site para to the N-methine carbon.
