摘要
Three cyclic disulfides were formed from linear analogs of calcitonin, epidermal growth factor (EGF), and a fragment of the DNA-binding Cro protein using a new reagent: cyanogen iodide (ICN). Each peptide contained two S-protected cysteine derivatives [Cys(Acm)] which were deprotected with concurrent disulfide bond formation. A comparison with I2, a common reagent for this reaction, is included.
