Abstract
Abstract Among the neutral products obtained on heating N-(-4-amino-pentanoyl)-4-aminopentanoic acid p-nitrophenyl ester in dilute pyridine solution are the lactam of 4-aminopentanoic acid and the cyclic tetramers of the amino acid. The 10-membered ring product of direct cyclization was not detected.
