摘要

An unprecedented domino synthesis of tetrahydrobenzofuran-4-ones is described implicating chemoselective alkylation of various 1,3-cyclohexanediones with bromocrotonate or crotonitrile followed by oxa-Michael cyclization. Further transformations of this core to reach molecular diversity are also presented.
