Abstract

The invention comprises tri-esters of a -keto-g -alkoxyaconitic acid and their preparation by reacting an ester of oxalacetic acid with an ester of trialkoxyacetic acid in the presence of an aliphatic carboxylic acid anhydride. Preferably the esterifying groups are lower alkyl groups of 1-6 carbon atoms. Specified esterifying groups are the methyl, butyl, hexyl, b -methoxyethyl and benzyl radicals. In an example, ethyl triethoxyacetate is treated with diethyl oxalacetate in the presence of acetic anhydride to give tri-ethyl a -keto-g -ethoxyaconitate.
