Enzyme-catalysed acetylation of either syn,syn- or anti,anti-2,4-dimet
hyl-1,3,S-pentane triol, easily obtained from a mixture of diastereome
ric 3-hydroxy-2,4-dimethylglutaric acids, proceeds stereoselectively w
ith preferential attack of the hydromethyl group linked to the R carbo
n atom of the starting triol, hence providing synthons useful for prep
aring compounds of the polypropionic pool. Copyright (C) 1996 Elsevier
