METHOD FOR PRODUCING 2 - (- G (V) -ALKOXYCARBONYLALKANOYL) -4-BUTANOLIDE AND LONG-CHAIN -G (V) -HYDROXYCARBOXYLIC ACID |
| abstract |
A 2-(φ-alkoxycarbonylalkanoyl)-4-butanolide is produced in a high yield with a good selectivity by the condensation reaction of η-butyrolactone with a readily available, inexpensive dicarboxylic ester represented by the following general formula: ROOC(CH2)nCOOR (wherein n is 7 to 13; and R represents alkyl or alkenyl). A long-chain φ-hydroxy carboxylic acid is produced by hydrolyzing and decarboxylating the above butanolide and reducing the carbonyl group of the obtained product into a methylene group. |
