摘要
A highly enantioselective method for the synthesis of 4-alkyl substituted 1,2,3,4-tetrahydroisoquinolines is reported. The key step relies on the asymmetric synthesis of alpha-alkylarylacetic acids by alkylation of their corresponding amides employing (S,S)-(+)-pseudoephedrine as chiral inductor. Subsequent Friedel-Crafts acylation, stereocontrolled reductive amination and Pictet-Spengler cyclization affords the title compounds in excellent yields and enantioselectivities.
