Abstract

As an extension of the application of enamide photocyclization to the synthesis of protoberberine alkaloids1 , new total syntheses of flavopereirine (6), one of the simplest alkaloids of Strychnos plants, and yohimbanes (11a, b, and c), the basic structures of the alkaloid yohimbine, are described.
