2-OXO-1,3-DIOXOLANE-4-CARBOXAMIDES, THEIR PRODUCTION AND APPLICATION Russian patent published in 2017 - IPC C07D317/38 C08K5/20 

FIELD: chemistry.

SUBSTANCE: invention relates to 2-oxo-1,3-dioxolane-4-carboxamides of formula (I), where R₁ and R₂, in each case independently of one another, are selected from H, unbranched or branched or cyclic groups of C_1-12-alkyl, and R₃ is H, or R₁ and R₃ each represents H, and R₂ is an n-valent radical in the form of unbranched or branched groups of C_2-22-alkylene, where n is 2-3, and which is substituted with n-1 additional groups of 2-oxo-1,3-dioxolane-4-carboxamide of the general formula (II), methods of preparing these 2-oxo-3-dioxolane-4-carboxamides based on 2-oxo-1,3-dioxolane-4-carboxylic acids of the formula (III), and also to the use of the said 2-oxo-1,3-dioxolane-4-carboxamides for the production of (poly) hydroxyurethanes, hydroxycarbonates and gidroxysulfonyl formiates, and as end groups for the blocking amines.

EFFECT: simplifying the process and increasing the yield.
