An efficient regiocontrolled synthesis of highly substituted and complex polycyclic benzo[b]thiophenes has been developed via our benzoannelation strategy involving conjugate addition-displacement on a variety of α-oxoketene dithioacetals by carbanions derived from 2- and 3-cyanomethylthiophenes followed by acid induced cyclization of the resulting conjugate adducts.
