cyclophosphamide, heated up to its melting point, the first pathway predominates over the second one. The structures of the phosphorus compounds were established by 1H and 31P NMR spectroscopy, and synthesis. The structure of the bicyclic compound 2 is confirmed by a single crystal X-ray diffraction study which allows an explanation for the selective and immediate hydrolysis with formation of a nine-membered
摘要 环磷酰胺在中性或微酸性水溶液中的降解开始于分子内烷基化,导致中间双环化合物立即水解为九元杂环。随后酸催化的 PN 键水解产生磷酸单酯。在强酸性溶液 (1 N HCl) 中,环磷酰胺仅分解为双 (2-氯乙基)-胺和相应的磷酸单酯 H2N(CH2)3OP(O)(OH)2。在加热到熔点的环磷酰胺固体样品中,第一种途径比第二种途径占优势。磷化合物的结构通过 1H 和 31P NMR 光谱和合成确定。
