The preparation and utilization of butenolide anion equivalents 5 and 6 in alkylation sequences is described. Treatment with CH3CO3H unmasks a latent butenolide moiety providing a general route to 3- and 4-alkyl 2(5H)-furanones.
描述了烷基化序列中丁烯酸内酯阴离子当量5和6的制备和利用。用CH 3 CO 3 H处理可掩盖潜在的丁烯内酯部分,从而提供通向3-和4-烷基2(5H)-呋喃酮的一般途径。
