Et3N mediated synthesis of polysubstituted thiophenes from α-oxo ketene dithioacetals
In this Letter, an efficient synthetic route to prepare polysubstituted thiophene derivatives was achieved via the Et3N-mediated (Claisen) rearrangement reaction from α-oxo S-methyl-S-propargyl ketenes, which were obtained through alkylation of

An expedient route to highly functionalized 2H-chromene-2-thiones via ring annulation of β-oxodithioesters catalyzed by InCl3 under solvent-free conditions
A convenient and one-pot synthesis of 3-aroyl/heteroaroyl-2H-chromene-2- thiones and benzo[f]2H-chromene-2-thiones has been developed by the condensation of β-oxodithioesters and salicylaldehydes/α-hydroxynaphthaldehydes in the presence of indium trichlor
