Abstract

Abstract An efficient, practical, and general method for conversions of N- tosyltetrahydroisoquinolines (N-tosyl-THIQs) into isoquinolines and of N-tosyltetrahydro-β- carbolines (N-tosyl-THBCs) into β-carbolines is described. Treatment of N-tosyl-THIQs or N- tosyl-THBCs with base in dimethyl sulfoxide afforded dihydroisoquinolines or dihydro-β- carbolines as intermediates, and these were then oxidized in situ by molecular oxygen to ...
