The resolution of racemic α-, β-, and γ-hydroxy-ω-alkenylphosphonates was achieved by enzymatic hydrolysis of the corresponding acetates. The optically active alcohols were transformed into β-hydroxyaldehydes and allowed to react with dihydroxyacetone phosphate (DHAP) via enzymatic aldol addition catalyzed by rabbit muscle fructose 1,6-bisphosphate aldolase (FruArab). After enzymatic dephosphorylation
外消旋 α-、β- 和 γ-羟基-ω-烯基膦酸酯的拆分是通过相应乙酸酯的酶水解来实现的。将光学活性醇转化为 β-羟基醛,并通过兔肌肉果糖 1,6-二磷酸醛缩酶 (FruArab) 催化的醛醇加成酶与磷酸二羟基丙酮 (DHAP) 反应。酶促去磷酸化后,获得了一组新的糖膦酸盐。
