An efficient method for the preparation of optically active derivatives of γ-amino-butenoic acids and their cyclic derivatives, 2-amino-pyrrolin-4-ones, from α-amino acids is described. Partial racemization accompanies the formation of initial unsa

A general synthesis of N-acetyl-3-alkanoyl- and 3-dienoyl-tetramic acids is presented. The condensation of N-(N-acetylglycyloxy)succinimide with β-keto esters bearing alkanoyl or dienoyl groups furnishes the new 3-substituted N-acetyltetramic acids
