摘要
合成了8种新的含3-芳亚甲基-4-芳基-2,3-二氢-1,5-苯并硫氮杂卓β-内酰胺衍生物.研究了它们的MS-EI谱,并就卓的合成以及MS-EI谱碎片的断裂方式进行了探讨.
Eight 3- arylidene-4- aryl-2,3-dihydro-1,5-benzothiazepine-β-Lactams derivatives were synthesized.
Electron impact-mass spectrum (MS) of these derivatives are reported. Their mass spectral fragmentation mechanism and reaction mechanism are proposed.
