Abstract

2‐Pyridine sulfenyl chloride (PS‐Cl) is a useful reagent for simultaneously deprotecting and activating the mercapto‐group of cysteine and of cysteine‐peptides preliminary to disufide‐bond formation. The S‐protecting groups that are amenable to this reaction include trityl, diphenylmethyl, acetamidomethyl, t‐butyl, and t‐butylsulfenyl.
