Abstract
1,198,414. 4-Acyloxybutyric acid esters. UGINE KUHLMANN. 13 Jan., 1969 [30 Jan., 1968], No. 1873/69. Heading C2C. The invention comprises esters of the formula in which R is a formyl, propionyl, isovaleryl, acetylsalicyl, phenylacetyl, cinnamoyl or (2- phenyl-2-ethyl) acetyl group and esters of the formula in which R<SP>1</SP> is a methyl, alkyl, benzyl or cyclopentyl group. They may be prepared by a general process for the preparation of 4-acyloxybutyric acid esters which comprises condensing an ester of a 4-halobutyric acid with the potassium salt of an organic carboxylic acid by fusion, preferably in the presence of an alkali metal iodide and/or an organic solvent, followed, if desired, by transesterification with an alcohol in the presence of a catalyst, e.g. aluminium isopropylate. Alkyl 4-chlorobutyrates wherein the alkyl group is methyl, ethyl or benzyl are prepared by reacting γ-butyrolactone with the appropriate alcohol and hydrogen chloride. Cyclopentyl- and alyl-4-chlorobutyrates are prepared by reacting 4-chlorobutyryl chloride with the appropriate alcohol.
