STUDIES ON PEPTIDES. XCVI. BEHAVIOR OF S-ACETAMIDOMETHYLCYSTEINE SULFOXIDE UNDER DEPROTECTING CONDITIONS IN PEPTIDE SYNTHESIS

The sulfoxide of Boc-Cys(S-acetamidomethyl)-OH was prepared by oxidation with sodium perborate.Mercuric acetate and iodine failed to cleave the S-protecting group from sulfoxide.Hydrogen fluoride and methanesulfonic acid partially converted the sulfoxide to S-p-methoxyphenylcysteine in the presence of anisole.A reducing reagent, thiophenol, converted the sulfoxide to acetamidomethyl phenyl sulfide and Nα-Boc-S-(phenylthio)cysteine.Keywords - S-acetamidomethylcysteine sulfoxide; mercuric acetate treatment; iodine treatment; hydrogen fluoride treatment; methanesulfonic acid treatment; thiophenol treatment
