1,3-Diacyl-2-hydroxy-5-alkyl- DELTA 2-pyrrolin-4-one derivatives (I) are new. The 1,3-Diacyl-2-hydroxy-5-alkyl- DELTA 2-pyrrolin-4-one derivatives are racemic and optically active compounds of formula (I) and their tautomers and salts: R<1> = acyl, preferably derived from an organic carboxylic acid; R<2> = alkyl, preferably 1-5C alkyl; and R<3> = acyl, preferably derived from an organic carboxylic acid. Independent claims are also included for the preparation of compounds (I). |
