The resolution of racemic α-, β-, and γ-hydroxy-ω-alkenylphosphonates was achieved by enzymatic hydrolysis of the corresponding acetates. The optically active alcohols were transformed into β-hydroxyaldehydes and allowed to react with dihydroxyacetone phosphate (DHAP) via enzymatic aldol addition catalyzed by rabbit muscle fructose 1,6-bisphosphate aldolase (FruArab). After enzymatic dephosphorylation
