Abstract

PURPOSE: To obtain a farnesylacetic acid ester, useful as an intermediate of medicine, e.g. anti-ulcerative, easily, in high yield with simple operation, by the heat- decomposition of farnesylmalonic acid diester in a specific solvent in the presence of a specific catalyst.
CONSTITUTION: A compound III is prepared by the heat-decomposition of a compound I (R is formula II; R1, R2 are alkyl or alkenyl), in the presence of hexamethylphosphoric triamide or a sulfur-containing solvent except dimethyl sulfoxide, e.g. dialkylsulfoxides, sulfolanes, sulfolenes, and sulfones, water and an alkali metal halide or cyanide. This method gives the compound III, a useful intermediate of an anti-ulcerative, geranyl farnesyl acetate, in one step in high yield, economically in an industrial scale.
