| titleOfInvention | METHOD FOR PRODUCING KETO ACIDS AND THEIR PRODUCTION |
| abstract | 1. A method of obtaining α-keto acids, as well as their derivatives of general formula (I) or (II)! ,,! where R1 denotes a branched or linear C1-C18 alkyl, C5-C8 cycloalkyl, vinyl, allyl, C6-C10aryl-C1-C4 alkylene or C4-C9heteroaryl-C1-C4 alkylene group and is optionally substituted,! R2 is -OR '' 'or -NR'R' ', where R' and R '' are the same or different and represent a hydrogen atom or a branched or linear C1-C6 alkyl group, and R '' 'is a hydrogen atom or branched or linear C1-C6 alkyl,! A C5-C8 cycloalkyl, allyl or benzyl group, wherein the alkyl in R ', R ″ and / or R ″ ″ is optionally substituted, or R ″ ″ is an alkali, alkaline earth or mono- or divalent transition metal ion,! R3 have the same or different meanings and represent a hydrogen atom or a branched or linear C1-C8 alkyl, allyl or benzyl group, where alkyl and / or benzyl are optionally substituted / substituted, or both R3 residues together are C2-C8 alkanediyl and together form a ring or both residues R3 and R "" together are part of the C3-C8 alkanthriyl group of the general formula -R3 (CH-) R "" - and together form a bicyclic group! a) the aldehyde R1CHO is reacted with the same or different thiols of the formula R4-S-H, where R4 is a branched or linear, optionally substituted C1-C6 alkyl, C5-C8 cycloalkyl, allyl or benzyl group to give the corresponding dithioacetal,! b) the formed dithioacetal is subjected to interaction with a carbonyl-containing electrophile in the presence of a strong base and |
