产品应用

  • 合成乌苯美司的中间体、多肽保护剂。广泛用于在以碳二亚胺类缩合剂进行的多肽缩合反应，可显著降低消旋比率，亦用于多肽片断缩合时防止消旋的产生。

相关文献及参考

  • Widely used additive which reduces racemization in the carbodiimide method of peptide coupling: Chem. Ber., 103, 788 (1970); J. Am. Chem. Soc., 93, 6318 (1971); Helv. Chim. Acta, 56, 717 (1973). The rate of peptide coupling is increased both in the solution method: Chem. Ber., 3626 (1973), and on solid supports: Tetrahedron Lett., 199 (1976). Addition of CuCl2 further reduces racemization: J. Chem. Soc., Chem. Commun., 419 (1988). A two-phase solvent system (DCM-water or isopropyl acetate-water) in conjunction with 1-(3-Dimethyl­aminopropyl)-3-ethyl­carbodiimide hydrochloride, A10807 (water-soluble carbodiimide), has been found to give superior results in this type of peptide coupling: J. Org. Chem., 60, 3569 (1995). Substoichiometric amounts (ca. 0.1 mol) of the additive in conjunction with the same coupling agent in DMF-water have been found to give good results: Chem. Lett., 1 (1997). The reagent also be used to form active esters with coupling as a separate step. For peptide reagents, see Appendix 6.
