The first example of the synthesis of 4,5‐disubstiuted furan‐2(5H)‐ones by base‐mediated tandem acyl shift/cyclization/decarbonylation reactions of aroylmethyl 2‐alkynoates has been developed. This new and inexpensive tandem route allows both a CO bond and a Csp3Csp2 bond forming in one step involving an unprecedented acyl rearrangement process.
已经开发出通过碱介导的芳烷基2-炔基酸酯的串联酰基转移/环化/去羰基化反应合成4,5-二取代的呋喃-2(5 H)-ones的第一个例子。这种新的和廉价的直通联接路由允许两个碳 O键和C的SP 3 Ç SP 2键在一个步骤涉及了前所未有的酰基重排处理形成。
