WebBOP-Cl was found to be an efficient coupling reagent for the introduction of thiopeptide bonds on imino acid residues (Pro, Sar). Boc-amino monothioacids were coupled at moderate temperature (0 degree C-RT) with fair yields and with retained optical purity. The mechanism of the coupling reaction is … WebMany coupling reagents are ineffective or not practical to use: BOP and HOBt are often useless; BOP-Cl, pivaloyl chloride and Dpp-Cl require … book manager software
