Abstract
The disclosure describes a method for the preparation of chiral vicinal aminoalcohols in high optical purity. The method combines the stereoselective reduction of the keto group of a .beta.-ketoacid, .beta.-keotester, or derivative with the stereospecific rearrangement of the corresponding amide, hyroxamic acid, or hydrazide to produce chiral vicinal aminoalcohols with control of stereochemistry at both chiral centers.
