摘要

根据乳酸合成旋光性3-烷基-5-甲基-2(5H)-呋喃酮的方法,以硬脂酸甲酯和棕榈酸甲酯为原料,分别与(R)-或(S)- o -四氢吡喃乳酸通过醛醇缩合直接合成了3-十四烷基和3-十六烷基-5-甲基-2(5H)-呋喃酮两对手性丁烯内酯。

Straightforward synthesis of two pairs of enantiomeric butenolides 3-tetradecyl- and 3-hexadecyl-5-methyl-2(5H)-furanone.
Based on the synthetic method of optically active 3-alkyl-5-methyl-2(5H)-furanones from lactic acid, two pairs of chiral butenolides 3-tetradecyl- and 3-hexadecyl-5-methyl-2(5H)-furanone have been straightforwardly synthesized from methyl stearate and methyl palmitate respectively by aldol condensation with (R)- or (S)-O-tetrahydropyranyl lactal prepared from corresponding ethyl lactate and beta-elimination.
