Using (−)-menthol as an auxiliary, three chiral vinylic epoxides have been synthesised from the corresponding glycidic esters via α-hydroxy-β,γ-unsaturated esters. Enzymatic resolution of α-acetoxy-β,γ-unsaturated esters using PLAP leads to optically active α-hydroxy- β,γ-unsaturated esters.
使用(-)-薄荷醇作为助剂,通过α-羟基-β,γ-不饱和酯由相应的缩水甘油酯合成了三种手性乙烯基环氧化合物。使用PLAP酶解α-乙酰氧基-β,γ-不饱和酯会产生旋光性α-羟基-β,γ-不饱和酯。
