Abstract

PURPOSE: To obtain a high purity isoprenyl acetic acid useful as a synthetic intermediate of isoprenyl acetic acid ester which is an antiulcerative, in high yield without side reactions, by the decarboxylation of isoprenyl malonic acid in the presence of a compound containing a basic metal.
CONSTITUTION: Isoprenyl acetic acid of formula II is obtained by the thermal decarboxylation of isoprenyl malonic acid of formula I (R is sioprenyl which means terpenehydrocarbon residue, e.g. formula III, formula IV, etc.) at 90W150°C in the presence of a compound containing a basic metal (preferably alkali metal alcoholate). The compound containing a basic metal is used in an amount of 0.001W0.5 times mol, preferably 0.003W0.05 times mol, based on the starting material. The compound of formula I is obtained by brominating isoprenyl alcohol, condensing the product with a sodium salt of dialkyl malonate, and hydrolyzing the condensate.
