    摘要: A process for making a compound of formula ##STR1## wherein R signifies a C.sub.1-23 -alkyl group or a C.sub.2-23 -alkenyl group containing 1 to 3 double bonds, comprising the steps of (a) reacting a compound of formula ##STR2## with an acylating agent which is in a mixture comprising (i) an organic solvent and (ii) a lipase which is present in suspension, so as to form the compound of formula I; and (b) recovering the compound of formula I is provided for. The process can be used to make (11Z,13Z)-7,10-dihydro-10-hydroxy-retinyl acetate, an starting material for the production of vitamin A acetate.
