Abstract
A Ga(OTf)(3)-promoted sequential reactions via sulfur-assisted propargyl-allenyl isomerizations and intramolecular [4 + 2] cycloaddition for the synthesis of 1,3-dihydrobenzo[c]thiophenes. As a result of the ready availability of materials and the simple and convenient operation, the type of reaction presented here has potential utility in organic synthesis.
