摘要

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 S(N)2 reaction.
