ABSTRACT:
2-oxoalkanoic acids are prepared by contacting an alpha-nitroketone with an alkanoic acid anhydride, such as acetic anhydride, and a tertiary amine, such as pyridine, thereby forming a 2-alkanoyloxy-2-alkenoic acid and thereafter hydrolyzing the alkenoic acid with an aqueous non-oxidizing acid, such as hydrochloric acid.
