Abstract
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.
