✦ Synopsis

Pseudomonas cepacaa ltpase catalyzes the acetylatton m orgamc solvent of dihydroxyaldehydes and ketones using vmyl acetate as acyl donor The method IS completely regoselecuve and allows to obtam partrally acetylated compounds different from those obtamed by enzymic hydrolysis of polyacetoxy arylaldehydes and ketones cepacia Irpase. The authors would also ltke to extend their thanks to MS C Rocco for performmg NMR spectra
