Here, we report a new approach of on-resin peptide ligation using C-terminal benzyl ester as the stabilized precursor of thioester, which enables both N-terminal elongation and C-terminal peptide ligation on a Rink Amide resin. On-resin native chemical ligation and auxiliary-assisted peptide ligation were successfully achieved. This method is compatible to both protected and unprotected peptide fragments and has potential application in poor water-soluble peptide ligation.

This protocol describes an iodine/manganese catalytic system for dehydrogenative oxidative coupling reaction of indoles with thiols in anisole. Particularly, the dual roles of anisole have been first demonstrated as a solvent and as a promoter via the formation of an oxonium ion intermediate to accelerate the generation of products. A series of sulfenylindoles are readily constructed under aerobic mild reaction conditions. In addition, the achievement for preparing anticancer and anti-AIDS drugs testifies the practicability of this approach. The mechanism studies disclose probable alternative pathways and a single-electron transfer process are involved in this transformation. (Figure presented.).
