Efficient Synthesis of Some Oxalacetic Acid and Pyruvic Acid Derivatives From the Reactions of 2,3-Furandiones With 2-Phenylindole

Abstract

Oxalacetic acid and pyruvic acid derivatives have been synthesized efficiently in high yields by the treatment of 4-ethoxycarbonyl-5phenyl-2,3-furandione and 4-benzoyl-5-phenyl-2,3-furandione with 2-phenylindole at room temperature and converted to simple derivatives such as an ester or a hydrazone.
