The structure I for Zizyphin (C33H49O6N5), a peptidic alkaloid isolated from the rootbark of Zizyphus oenoplia MILL., has been determined by chemical degradation and confirmed by N.M.R. investigation. The stereochemistry of Zizyphin has been elucidated with the exception of the configuration of the ether group of the hydroxyproline unit, which is expected to belong to the natural series.
Zizyphin(C 33 H 49 O 6 N 5)的结构I ,是一种通过化学降解方法确定并从NMR研究中证实的物质,该肽类生物碱是从Zizyphus oenoplia MILL。的根皮中分离出来的。阐明了zyzyphin的立体化学,只是羟基脯氨酸单元的醚基团的构型是预期的,该构型属于自然系列。
