Canadine (4) has been synthesised by methylation of nandinine (3), prepared from 1,2,3,4-tetrahydro-1-(3-hydroxy-4-methoxybenzyl)-6,7-methylenedioxyisoquinoline (13) by a Mannich reaction. This Mannich reaction was studied under various conditions and the structure of an abnormal product, 9-hydroxy-12-hydroxymethyl-10-methoxy-2,3-methylenedioxyberbine, (7) has been elucidated.
Canadine(4)是通过Mannich由1,2,3,4-四氢-1-(3-羟基-4-甲氧基苄基)-6,7-亚甲基二氧基异喹啉(13)制备的嘌呤(3)甲基化而合成的反应。在各种条件下研究了该曼尼希反应,并阐明了一种异常产物的结构,即9-羟基-12-羟甲基-10-甲氧基-2,3-亚甲基二氧基小b碱(7)。
