In order to determine the configuration of the diastereoisomers of the dipeptide analogues L-Pro ψ(CHCH, E) L,D-Phe, a method is described involving reduction of the ethylenic bond and cyclization to the lactams. The 1H NMR spectra of the separated isomers allow the assignment of the S,S or R,S configuration.
为了确定二肽类似物L-Proψ(CH = CH,E)L,D-Phe的非对映异构体的构型,描述了一种方法,该方法涉及烯键的还原和环化为内酰胺。分离的异构体的1 H NMR光谱可以指定S,S或R,S构型。
