Boron Trifluoride Etherate Promoted Regioselective 3-Acylation of Indoles with Anhydrides

ABSTRACT: An efficient, high-yielding and scalable procedure for the regioselective 3-acylation of indoles with anhydrides promoted by boron trifluoride etherate under mild conditions was reported. This novel protocol provided a simple way to prepare 3-(benzofuran-2-yl) indole in three steps.
