The disclosure describes a process for the preparation of cyclic optically active amino alcohols of formula (I) by reacting an optically active hydroxycarboxylate of formula (IV) with hydrazine to form an optically active hydroxycarboxylic hydrazide compound of formula (III), then conducting a Curtius reaction in the presence of an alcohol to give an optically active alkoxycarbonylamino alcohol of formula (II), followed by deprotecting the amino group to form the amino alcohol of formula (I).
The variables A1, A2, R1-R6, m, n and * are as defined in the claims.
