First total synthesis of the phenolic protoberberine, cerasonine, was accomplished through a coupling reaction between o-toluamide and benzonitrile. This key step provided the 3-arylisoquinoline which was then successfully converted to 7,8-dihydro-8-oxoprotoberberine through an intramolecular SN2 reaction.
通过邻甲苯酰胺和苯甲腈之间的偶联反应,首次完成了酚类原小檗碱--cerasonine 的全合成。这一关键步骤提供了 3-芳基异喹啉,然后通过分子内 SN2 反应成功地将其转化为 7,8-二氢-8-氧代原小檗碱。
