Continuous-flow processes for the S-alkynylation of cysteine-containing peptides and thioglycosides under catalyst-free, oxidant-free and mild conditions
selective alkylation of cysteine-containing peptides in a continuousflow reactor has been developed, providing an efficient pathway to alkylated cysteine-containing peptidesunder mild conditions. This process does not need light, metal catalysts, or oxidative reagents. It provides a useful method for the modification of amino acids and peptides. As one of the low cost and synthetic versatile raw materials
