摘要
以5,7-二羟基黄酮和磷酰化氨基酸酯为原料,利用磷酰化反应将磷酰化氨基酸酯引入到白杨素中,得到了一种新型的白杨素-7-氨基磷酸酯衍生物.通过DEPT、1H-1H COSY、13C-1HHSQC和13C-1H HMBC等2DNMR核磁共振技术对该化合物的1H、13C NMR谱的信号进行了全归属和较详细的解析,并探讨了其ESIMS/MS质谱裂解规律.
In this study, sin to form a novel chry the phosphorylated glycine methyl ester was coupled with chrysin-7-yl phosphoramidate derivative by a facile phosphorylated reaction. Complete assignment of the ^1H and ^13C NMR chemical shifts of the synthe- sized compound was obtained by 2D NMR techniques, including DEPT, ^1H-^1H COSY, ^13C-^1H HSQC and ^13C-^1H HMBC. ESI MS/MS spectra of the compound were also recorded and used to study its fragmentation behaviors.
