Mild Reductive Cleavage of the 9-Anthracenesulfonamido Function. The 9-Anthracenesulfonyl (Ans) Group: A New Approach to the Protection of the Guanidino Function of Arginine Residues in Peptide Synthesis

Article abstract of DOI:10.1055/s-1988-27457

Convenient syntheses of L-arginine derivatives bearing the 9-anthracenesulfonyl (Ans) protective group at the ω-guanidino site are described.Simple arginine-containing peptides bearing the Ans group are shown to be stable to the normal conditions of pepti
