The disclosure describes a method for the preparation of chiral 1,3-aminoalcohols in high optical purity. The method combines the stereoselective oxidation of a 1,4-diol to a gamma-lactone using an alcohol dehydrogenase, the conversion of the gamma-lactone to the corresponding 4-hydroxyamide, 4-hydroxyhydroxamic acid, or 4-hydroxyhydrazide, and stereospecific rearrangement of the 4-hydroxyamide, 4-hydroxyhydroxamic acid, or 4-hydroxyhydrazide to the corresponding chiral 1,3-aminoalcohol.
该披露描述了一种制备高光学纯度手性1,3-氨基醇的方法。该方法结合了使用醇脱氢酶对1,4-二醇进行立体选择性氧化成γ-内酯,将γ-内酯转化为相应的4-羟基酰胺、4-羟基羟肟酸或4-羟基肼,并对4-羟基酰胺、4-羟基羟肟酸或4-羟基肼进行立体特异性重排,得到相应的手性1,3-氨基醇。
