摘要: A compound (I) is prepared by reacting at least one (meth)acrylate (II) with a heterocyclic alcohol (III), in the presence of a catalyst consisting of a mixture formed (a) of at least one magnesium alkoxide and (b) of a component chosen from the chelates of calcium with 1,3-dicarbonyl compounds, dialkyltin oxides, dialkyltin alkoxides and dialkyltin diesters. ##STR1## R=C.sub.1 -C.sub.4 alkyl. R.sup.1 =H, CH.sub.3 ; A, B=straight or branched C.sub.2 -C.sub.5 hydrocarbon chain; R.sup.2 =C.sub.1 -C.sub.4 alkyl.
