Abstract: A process for the preparation of amino alcohols includes condensing a compound of Formula (II), a stereoisomer, a tautomer, or a salt thereof with a compound of Formula (IIIa) or Formula (IIIb), a stereoisomer, a tautomer, or a salt thereof to form a condensation product; hydroxylating or acyloxylating the condensation product in the presence of an oxidant to obtain a hydroxylation or acyloxylation product; and subjecting the hydroxylation or acyloxylation product to one or more subsequent reactions comprising a hydrolysis reaction, alcohol deprotection, an amino lysis reaction, or a combination of two or more thereof to obtain an amino alcohol of Formula (I).
