摘要
Generation of a library using parallel syntheses of multi-substituted benzo[b]thiophenes is described. The requisite 3-iodobenzo[b]thiophenes are readily prepared in excellent yields from various alkynes bearing electron-rich aromatic rings by electrophilic cyclization using I-2 in CH2Cl2. The heteroaromatic carbon-iodine bonds allow further diversification by palladium-catalyzed Suzuki-Miyaura, Sonogashira, Heck, and carboalkoxylation chemistry to give multi-substituted benzo[b]thiophene derivatives.
