Abstract: Ethylenically unsaturated glycosides of formula (I) wherein n, A, X, R3 and R4 have 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 glycosidase, such as an amylase, cellulase, glucosidase or galactosidase, (i) at a molar ratio of ethylenically unsaturated alcohol of formula II to saccharide of formula (III) of from 2:1 to 30:1; (ii) in the presence of a solvent mixture of water and a water miscible organic solvent that is no primary or secondary alcohol, such as acetone, acetonitrile, t-pentanol, t-butanol, 1,4-dioxane and tetrahydrofuran, at a weight ratio of water to organic solvent of from 0.1 :1 to 9:1; and (iii) at a weight ratio of solvent mixture to saccharide of from 3:1 to 30:1.
