Ethylenically unsaturated glycosides of the formula I: wherein n, A, X, Rand Rhave the meanings given in the description are produced by reacting an ethylenically unsaturated alcohol of formula II: with a saccharide of formula III: in the presence of a glucosidase at a molar ratio of the alcohol to the saccharide of from 2:1 to 30:1 in the presence of a solvent mixture of water and 1,4-dioxane at a weight ratio of 0.1:1 to 9:1 and a weight ratio of solvent mixture to saccharide of from 3:1 to 30:1.

Enzymatic production of an ethylenically unsaturated glycoside

Ethylenically unsaturated glycosides of formula I wherein Y, Y', m, A, X, Rand Rhave the meanings given in the description, are produced by reacting an ethylenically unsaturated compound of formula II with a polysaccharide comprising 10 or more monosaccharide units, such as starch, amylose, amylopectin, cellulose,in the presence of a glycosidase, such as an amylase, cellulase, glucosidase or and galactosidase, or a glycosyltransferase, such a cyclomaltodextrin glucanotransferase.
