Application
TMS-N-ethynyl-N,4-dimethylbenzenesulfonamide (TMS-MTYsA) is an air- and moisture-stable ynamide demonstrated to be an efficient and high-yielding coupling reagent for selective amide and peptide bond formation under mild reaction conditions without racemization. The product is supplied as the TMS-protected ynamide, which can be easily deprotected in situ without isolating the product.
