| titleOfInvention | Method for producing 2 (5H) -furanone derivative |
| abstract | (57) [Summary] (Modified) [Objective] To provide a method for synthesizing a 2 (5H) -furanone derivative easily and in high yield. [Structure] The compound represented by the general formula (I) is diluted with an inert organic solvent, and reacted in the presence of an equal amount of a base under an acidic condition using an excess amount of the acid represented by the general formula (II). The intermediate represented by the general formula (III) is thereby synthesized, and then the temperature of the reaction solution is adjusted to −10 to 25 ° C. and an organic base is added. When intermediate (III) disappears by 90% or more, The reaction is stopped by making the reaction solution acidic. A method for producing a 2 (5H) -furanone derivative represented by the general formula (1V). R-COCH 2 X 1 formula (I) X 2 -CH 2 COOH Formula (II) R-COCH 2 OCOCH 2 X 2 formula (III) [In the formula, R represents an alkyl group, an aryl group, a heterocycle, etc., X 1 represents a halogen atom, and X 2 represents an electron-withdrawing group (particularly preferable is a cyano group)] |
