Here we describe the development of a high-yielding, one-pot ligation-desulfurization protocol that uses trifluoroethanethiol (TFET) as a novel thiol additive. The synthetic utility of this TFET-enabled methodology is demonstrated by the efficient multi-step one-pot syntheses of two tick-derived proteins, chimadanin and madanin-1, without the need for any intermediary purification.

Solubilizing trityl tags (Trt-oligoLys/Arg) proved applicable to metal-free radical-triggered desulfurization and an Ag-mediated thioester method. Additionally, using the solubilizing trityl tag strategy, synthesis of the influenza BM2 proton channel, which previously required organic solvent-aided native chemical ligation (NCL) and desulfurization due to its low solubility, was achieved without using organic
