METHOD FOR OBTAINING GLYCOSIDES OF ACRYLATE DERIVATIVES WITH APPLICATION OF SACCHARIDES AND GLYCOSIDASES Russian patent published in 2016 - IPC C12P19/44 C07H15/04 C07H15/10

Abstract RU 2575609 C2

FIELD: chemistry.

SUBSTANCE: invention relates to field of biotechnology. Claimed is method for obtaining ethylene-unsaturated glycoside of formula I , where n, A, X, R³ and R⁴ have values, given in the formula. Formula I glycoside is obtained by reaction of ethylene-unsaturated alcohol of formula II with saccharide of formula III in presence of β-glucosidase. Molar ratio of ethylene-unsaturated alcohol of formula II to saccharide of formula III constitutes from 2:1 to 30:1. Reaction is carried out in presence of mixture of solvents, consisting of water and 1,4-dioxane. Weight ratio of water and 1,4-dioxane constitutes from 0.1:1 to 9:1. Weight ratio of mixture of solvents to saccharide constitutes from 3:1 to 30:1.

EFFECT: invention makes it possible to increase output of ethylene-unsaturated glycoside after certain time of reaction process and/or when equilibrium is achieved.
