An extensive survey by the use of high performance liquid chromatography on racemization during the coupling of benzyloxycarbonyl-L-phenylalanyl-L-valine with L-proline tert-butyl ester.

Peptides were produced in high yields and, if any, very low epimerization, by mechanochemical coupling of peptide fragments containing highly epimerization-prone and/or highly hindered amino acids at C-term. Ball milling was clearly identified as the key element enabling one to obtain such results.
通过在 C 端含有高度差向异构化和/或高度受阻氨基酸的肽片段的机械化学偶联,以高产率和(如果有的话)非常低的差向异构化产生肽。球磨被清楚地确定为获得这种结果的关键因素。
