sodium hypochlorite afforded cis- and trans-3-chloro-4-phenylcyclophosphamide and 3-chloro-5,6-benzocyclophosphamide, respectively. 31P-NMR spectroscopy was used to study the reactivity of these compounds: the fluoro derivative was reduced to cyclophosphamide on incubation with mouse liver slices, and the reactivity order for sulfhydryl-induced reduction of the 3-halocyclophosphamides was Br approximately
由三氟甲基次萤石,次氯酸钠和溴与抗癌药环磷酰胺反应制得3-氟,3-氯和3-溴环磷酰胺。用次氯酸钠处理顺式和反式-4-苯基环磷酰胺和5,6-苯并环磷酰胺分别得到顺式和反式3-氯-4-苯基环磷酰胺和3-氯-5,6-苯并环磷酰胺。31 P-NMR光谱用于研究这些化合物的反应性:与小鼠肝切片一起孵育时,氟衍生物被还原为环磷酰胺,巯基诱导的3-卤代环磷酰胺还原的反应级数Br约等于Cl,与环磷酰胺对小鼠L-1210和P-388癌症的治疗效果相比,3-氟-和3-氯环磷酰胺的活性较低,尽管氟衍生物比3-氯化合物更有效。分别由(S)-和(R)-环磷酰胺制得的3-氯环磷酰胺的各个R和S对映体在P-388测试系统中的治疗活性无明显差异。
