An efficient, high-yielding and scalable procedure for the regioselective 3-acylation of indoles with anhydrides promoted by borontrifluorideetherate under mild conditions was reported. This novel protocol provided a simple way to prepare 3-(benzofuran-2-yl) indole in three steps.
A general synthesis of arylindoles and (1-arylvinyl)carbazoles via a one-pot reaction from N-tosylhydrazones and 2-nitro-haloarenes and their potential application to colon cancer
An efficient and one-potsynthesis of 3,3′-bisbenzofuran derivatives has been developed. The protocol involved the use of a Pd catalyst and Cu(OAc)2 along with molecular oxygen as the oxidant to afford bisbenzofurans via a dehydrogenative homo-coupling reaction. The reaction exhibited good functional group/heterocycle tolerance and is amenable for gram scale synthesis.
