1301514 Cystine-peptides FARBWERKE HOECHST AG 7 April 1970 [9 April 1969] 16454/70 Heading C2C A cystine-containing peptide is prepared by ticating a corresponding peptide having at least one S-trityl cystine group with 1-2 moleequivalents of iodine in aqeuous acetic acid. The following starting materials are prepared: BOG and H-Cys(Trit)-Gly ONB; BOCLeu - Cys(Trit) - Gly ONB and H - Liu - Cys- (Trit) - Gly OH; BOC - Val - Cys(Trit) - OH DCHA; BOC - Val(Trit) - Ala - ONB; and H - Val - Gys(Trit) - Ala - OH.
