Patent ID: 7767425

Claim:
A process for the enzymatic synthesis of 6-O-acryloyl C 1-30 alkyl glycosides comprising reacting a C 1-30 alkyl glycoside compound with an acrylic acid compound or an alkyl ester thereof in a liquid reaction medium comprising a solvent in the presence of an acrylate-transferring enzyme at a temperature suitable for effecting the reaction, thereby producing the 6-O-acryloyl C 1-30 alkyl glycoside, wherein the solvent is an organic solvent, wherein the organic solvent is present in an amount of 0.01 to 4 ml per mmol of the C 1-30 alkyl glycoside compound, wherein the acrylic acid compound or the alkyl ester thereof and the C 1-30 alkyl glycoside compound are in a molar ratio of 10:1 to 3:1; wherein the acrylic acid compound or alkyl ester thereof is selected from the group consisting of acrylic acid, acrylic acid substituted by C 1 -C 6 alkyl groups, and the C 1 -C 6 alkyl esters thereof wherein the enzyme is selected from the group consisting of lipases according to E.C.3.1.1.3 that is free or immobilized in said liquid reaction medium; and wherein the enzyme content in the liquid reaction medium is in the range from 0.1 to 10% by weight of the C 1-30 alkyl glycoside compound.
