A convenient synthetic strategy to obtain viniferifuran and (+/-)-dehydroampelopsin B analogues based on the heterocyclic cores of indole, benzo[b]thiophene, and benzo[b]selenophene is presented. The key transformations utilized in the described syntheses include Sonogashira couplings, Cacchi and alkyne electrophilic cyclizations, Horner-Wadsworth-Emmons (HWE) reaction, chemoselective Suzuki-Miyaura couplings, and acid-promoted intramolecular cyclization to form the sevenmembered ring of (+/-)-dehydroampelopsin B.
