Abstract

Enamide photocyclization has been shown to be a new and useful tool for the synthesis of various nitrogen-containing heterocyclic systems, particularly alkaloids. By this means, the synthesis of crinan, benzo(c)phenanthridine, aporphine, protoberberine and yohimbine alkaloids has been achieved.
