Abstract

From Nα-trityl-L-arginine benzyl ester, Nω-glycyl-, Nω-L-valyl-, and Nω-L-arginyl-L-arginine have been prepared. These non-typical arginine peptides were transformed, especially in alkaline solution, into ornithine and the corresponding 2-iminoimidazolidin-4-one (glycocyamidine) derivatives. In this way the suggestion of Zervas and Bergmann that a non- typical Nω-L-arginyl-L-arginine is formed as an intermediate in the disproportionation of ...
