Synthesis of benzothiophene and indole derivatives through metal-free propargyl–allene rearrangement and allyl migration

An efficient base-catalyzed protocol for the synthesis of benzothiophene is described. The reaction proceeds via base-promoted propargyl–allenyl rearrangement followed by cyclization and allyl migration. Phosphine-substituted indoles can be synthesized by a similar strategy.
