METHOD OF PRODUCING n-(N-GLUCOSYLIDENE)AMINOBENZOIC ACID ESTERS Russian patent published in 2014 - IPC C07H5/06

Abstract RU 2529022 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing n-(N-glucosylidene)aminobenzoic acid of general formula: (where R is a straight or branched aliphatic radical with 1-9 carbon atoms), which can be used as sunscreen agents in cosmetics and as biologically active substances in medicine. The method includes hydrogenation of corresponding esters of n-nitrobenzoic acid and condensation of the obtained amines with glucose in one reactor at 20-55°C (preferably 45°C) in the presence of a AB-17-8- Pd catalyst (CH₃COO^- form).

EFFECT: invention enables to obtain end products using a simple method.
