Synthetic studies of aryl-l,2,3,4-tetrahydroisoquinolines have attracted much attention from the synthetic community owing to the potential biological activities of this class of compounds and their increasing medicinal interest. The alkaloid cherylline is a naturally occurring optically active, 4-aryl-1,2,3,4- tetrahydroisoquinoline alkaloid, isolated from Crinum Powellii, Amaryllidaceae plant. There are many ways for cherylline synthesis. An application of Bischler-Napieralski reaction for the synthesis of new 1,4-disubstituted- 1,2,3,4- tetrahydroisoquinolines as cherylline derivatives, is described
