Abstract
One pot synthesis of title compounds is reported involving the condensation and oxidative cyclization of 2-aminobenzenethiols with benzyl acetoacetate (P-keto ester) in dimethyl sulfoxide. The structures of the title compound s have been characterized by analytical, IR, NMR and Mass spectral data.
