Abstract

p-Toluenesulfonic acid mediated formal [3+3] cyclization of 3-indolylmethanols with 3-isothiocyanato oxindoles was realized. This transformation allowed for the synthesis of a series of novel tetrahydro-β-carboline-1-thione spirooxindoles in moderate to excellent yields (up to 99%) with generally good diastereoselectivities (up to >20:1). The structure of one product was determined by an X-ray crystal structural analysis.
