Selective synthesis of oxygen-containing heterocycles via tandem reactions of 1,2-allenic ketones with ethyl 4-chloroacetoacetate

Abstract

By tuning the reaction conditions and the substitution patterns of substrates, the selective synthesis of oxepin-3(2H)-ones, benzo[d][1,3]dioxoles, or furan-3(2H)-ones starting from readily available acyclic substrates under mild conditions has been established.
