说明

一般說明

PyOxim ^[1] is a novel reagent which mediates coupling reactions with efficiencies superior to HATU and PyBOP and comparable to COMU. It is has excellent solubility in DMF and is stable in solution under an inert atmosphere for two days. Unlike HATU and HBTU, it cannot cause chain terminating side reactions and is, therefore, ideal for the synthesis of cyclic peptides. Furthermore, it is not explosive under normal operating conditions and is less likely to exhibit allergenicity compared to other coupling reagents.

特點和優勢

• Mediates coupling with superior efficiency to PyBOP, TBTU, and HCTU
• Mediates coupling with low racemization or epimerization
• Ideal for fragment condensation and synthesis of cyclic peptides as the reagent cannot cause guanidinylation
• Excellent solubility in DMF and NMP
