Abstract

Abstract t-Leucine has been conveniently prepared on a large scale from the phenylhydrazone of trimethylpyruvic acid, which was readily obtained as a precipitate from the oxidation of pinacolone. The N-benzyloxycarbonyl derivative of Dl-t-leucine has been resolved with quinine and quinidine in ethanol.
