摘要：An aldehyde (R.sup.1 CHO) and optically active 3- hydroxybutyric acid (CH.sub.3CH(OH)CH.sub.2 COOH) are reacted to form an optically active dioxanone. This dioxanoneis reacted with a compound R. sup.2 --X to form an intermediate (R.sup.1 R.sup.2CHOCH(CH.sub.3) CH.sub. 2 COOH) which is then subjected to elimination to form anoptically active secondary alcohol (R.sup.1 R.sup.2 CHOH) in good yield and purity.
