found to be an excellent coupling reagent having a water-soluble property and a high reactivity; it worked as satisfactory as usual active esters in regard to the reactivity, product purity, and racemization. The marked advantage of the HODMSP·MeSO4− active ester method was the fact that bifunctional residues such as Arg, Lys, Cys, and Tyr could be selectively acylated when the pH of the reaction mixture
发现(对羟基苯基)二甲基锍甲基硫酸盐(HODMSP·MeSO4-)是一种优良的偶联剂,具有水溶性和高反应性;在反应性、产品纯度和外消旋化方面,它与通常的活性酯一样令人满意。HODMSP·MeSO4-活性酯法的显着优势在于,当反应混合物的pH值得到控制时,双功能残基如Arg、Lys、Cys和Tyr可以被选择性地酰化。通过这种新的活性酯方法合成了软体动物神经肽 FMRFamide(Phe-Met-Arg-Phe-NH2),以评估该方法在涉及肽合成的进一步应用中的应用。
