γ-heterosubstituted γ-methyl-α,β-butenolides are presented, starting mainly from C3 synthons (glyceraldehyde, glycidaldehyde, acrolein and 2,3-epoxypropyl ethers). Good general methods for the preparation of γ-hydroxymethyl-α,β-butenolide 2, several of its ether derivatives, as well as of γ-bromomethyl-α,β-butenolide 5, are given. The reactivities of these structurally simple but highly functionalized compounds
提出了穷举的合成外消旋γ-杂取代的γ-甲基-α,β-丁烯化物的方法,主要从C 3合成子(甘油醛,缩水甘油醛,丙烯醛和2,3-环氧丙基醚)开始。给出了制备γ-羟甲基-α,β-丁烯醇内酯2,其几种醚衍生物以及γ-溴甲基-α,β-丁烯醇内酯5的良好通用方法。初步探讨了这些结构简单但功能化程度高的化合物的反应性,即用于更复杂分子的便利合成子。
