A process for producing an (S)-γ-acyloxy-methyl-α, β-butenolide characterized by using a 2-alkoxy-6-acyloxymethyl-2H-pyran-3(6H)-one as the starting material and oxidizing it with a peracid in an organic solvent. The objective compound can be obtained in a high yield from D-glucose which occurs naturally in abundance, because the starting material can be prepared from D-glucose.
一种生产(S)-γ-乙酰氧基-甲基-α,β-
丁烯内酯的工艺,其特征在于使用 2-烷氧基-6-乙酰氧基甲基-
2H-吡喃-3(6H)-酮作为起始原料,并在有机溶剂中用过酸将其氧化。由于起始原料可以从天然存在的大量
D-葡萄糖中制备,因此可以从
D-葡萄糖中高产率地获得目标化合物。
