Abstract

Abstract An efficient synthesis of paullone and kenpaullone derivatives in moderate to high yields has been achieved through photocyclizations of (2-chloro-1H-indole-3-yl)-N- arylacetamides in acetone at room temperature. Paullone and kenpaullone have been obtained easily and in high yields by deprotection of the photocyclization products.
