摘要

Abstract A new and convenient metal-free cyclization of ortho-hydroxystilbenes into 2- arylbenzofurans and 2-arylnaphthofurans mediated by hypervalent iodine reagents is described. The cyclization products are isolated in good to excellent yields using stoichiometric (diacetoxyiodo) benzene in acetonitrile.
