Activated cyclophosphamide analogues having a 4-hydroperoxy-1, 3, 2-diazaphos-phorinane-2-oxide ring were synthesized by ozonolytic cyclization reaction of N-3-butenyl-phosphorodiamidates. Stereochemistries of the 1, 3, 2-diazaphosphorinane derivatives were investigated by proton magnetic resonance (PMR) spectroscopy. Both the chemical and PMR properties of these derivatives were similar to those of the corresponding 1, 3, 2-oxazaphosphorinane derivatives. The 1, 3, 2-diazaphosphorinane derivatives practically had no antileukemic activity against L1210-BDF1 mice, providing a further evidence that the 1, 3, 2-oxazaphosphorinane ring of cyclophosphamide-related compounds is not replaceable by other ring systems for promoting antitumor activity.
通过臭氧裂解环化反应合成了具有4-氢过氧基-1, 3, 2-二氮杂膦烷-2-氧环的活化环磷酰胺类似物。采用质子核磁共振(PMR)光谱法研究了1, 3, 2-二氮杂膦烷衍生物的立体化学。这些衍生物的化学和PMR性质与相应的1, 3, 2-氧杂膦烷衍生物相似。1, 3, 2-二氮杂膦烷衍生物对L1210-BDF1小鼠几乎没有抗白血病活性,这进一步证明了环磷酰胺相关化合物的1, 3, 2-氧杂膦烷环不能被其他环系替代以促进抗肿瘤活性。
