Abstract
Abstract A selective and efficient method for disulfide bond formation in peptides utilizing carbon tetrachloride in dichloromethane in the presence of tetrabutylammonium fluoride (TBAF) is described. The reaction proceeded rapidly and no side reaction was observed with nucleophilic amino acids such as Met, His, Tyr or Trp. This method has been applied to three model peptides using solution and on-the-resin disulfide formation.
