摘要

A variety of furan-2-ylacetates have been prepared by dehydrogenation of monocyclic 2- alkylidenetetrahydrofurans, which are readily available by cyclizations of open-chained 1, 3- dicarbonyl dianions with 1-bromo-2-chloroethane. 5'H-[2, 3'] Bifuranyl-2'-ones are available based on sequential “cyclization/dehydrogenation” reactions of α-acetyl-γ-butyrolactones. A variety of 7-(alkoxycarbonyl) benzofurans and 7-(alkoxycarbonyl)-2, 3- ...
