An investigation was performed on the formation of amides and substituted amides of N-(9-fluorenylmethoxycarbonyl) di-, tri-, tetra-, penta- and hexapeptide acids with the crystalline ammonium, methylammonium, ethylammonium and benzylammonium salts of N-hydroxysuccinimide, and also on the rates of racemization in the amidation process. The precise stereochemical purities of the products were measured by conventional HPLC, using pre-column derivatization with Marfey’s reagent, and proved to be on average 98%.
研究人员对 N-(9-芴甲氧羰基)二肽、三肽、四肽、五肽和六肽酸与 N-羟基琥珀酰亚胺的结晶铵盐、甲铵盐、乙铵盐和苄铵盐形成的酰胺和取代酰胺进行了研究,并对酰胺化过程中的消旋化率进行了研究。利用马菲试剂进行柱前衍生,通过传统的高效液相色谱法测量了产品的精确立体化学纯度,结果表明平均纯度为 98%。
