dc.description.abstract
(Chemical Equation Presented) The reaction of N-tosyltryptamines with thioortho esters, leading to 1-thiosubstituted tetrahydro-β-carbolines under modified Pictet-Spengler conditions, is described. The 1-heterosubstituted β-carbolines furnished 1-substituted β-carbolines upon reaction with Grignard reagents and silyl derivatives under Lewis acid promotion.
