Abstract
An efficient strategy for the construction of 3-sulfenylindoles and 3-arylindoles based on a one-pot relay Sc(III)/base-promoted Michael addition/cyclization/aromatization process has been developed. Different types of nucleophiles (thio- and carbon nucleophiles) react with aza-alkynyl o-quinone methides (aza-o-AQMs) generated in situ from 1-(o-aminophenyl)prop-2-ynols to afford the indole derivatives in moderate to excellent yields. This method displays the advantages of mild conditions, simple starting materials, and broad substrate scope.
