Abstract
Metal-free para-toluenesulfonic acid mediated straightforward synthesis of hitherto unreported tetrasubstituted thiophenes has been achieved in quantitative yields by chemo- and regioselective dehydrative cyclization of α,α′-bis(β-oxodithioesters) at room temperature. Notably, the dithioester group at the 4-position of the thiophene ring has been further transformed to a thiazoline group.
