Abstract

Abstract An improved route has been devised which provides canthin-6-one in the highest yield from tryptamine to date. Tryptamine is converted to Nb -benzyltryptamine via reaction with benzoylchloride and reduction using LAH. Pictet-Spengler condensation with 2-ketoglutaric acid, removal of the protecting group by CTH, and aromatization with MnO2 affords canthin-6-one in 48% overall yield.
