CA 2940166 ABSTRACT 2-Acetoxyalkanoic acid esters are made in a reaction of an crhydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivi...

Zusammenfassung:CA 2940166 ABSTRACT 2-Acetoxyalkanoic acid esters are made in a reaction of an crhydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product. For example, the 2-acetoxyalkanoic acid ester may be of the formula: 0 H3C/.\ 0 ...õ..0,, Ri R2, R3 0 Date Recue/Date Received 2021-02-10 Des esters d'acide 2-acétoxyalcanoïque sont obtenus à l'issue de la réaction d'un ester d'acide alpha-hydroxyalcanoïque et d'un ester d'acétate en présence d'un catalyseur de transestérification. Contrairement aux précédents procédés de production d'esters d'acide 2-acétoxyalcanoïque, ce procédé présente un rendement élevé en produit recherché et une grande sélectivité.
