摘要

Convenient syntheses of L--arginine derivatives bearing the 9eanthracenesullonyl (Ans) protective group at the w-guanidino site are described. Simple arginine-containing peptides bearing the Ans group are shown to be stable to the normal conditions of peptide synthesis. The Ans group is removed either by acidolysis with trifiuoroacetic acid over a period of hours or by a variety of novel, mild reducing conditions including reaction with alurninuin ...
