Abstract

NaCl significantly enhanced the longer oligoarginine formation in the oligomerization of L‐arginine activated by N,N′‐carbonyldiimidazole (CDI) in homogeneous aqueous solution. The optimal concentration of NaCl for the highest yield of longer oligoarginine formation is around 1__M__. It is suggested that the weak interactions of Cl^−^ with the positive‐charged guanidinium group of the oligoarginines formed in the oligomerization of L‐arginine are responsible for the enhancement by NaCl. © 2005 Wiley Periodicals, Inc.
