Partial demethylation of homoveratronitrile (3a) with Lewis acids affords a mixture of the isomeric monophenols 3b and 3c. Separation of the isomers offers a new approach to N‐norreticuline (1a) and its 6′‐halogen derivatives 1b,c.
用路易斯酸部分去甲基化高过四腈 (3a) 得到异构单酚 3b 和 3c 的混合物。异构体的分离为 N-去甲网状番荔枝碱 (1a) 及其 6'- 卤素衍生物 1b、c 提供了一种新方法。
