The ifosfamide metabolite isophosphoramide mustard (IPM) was synthesized with isotopic enrichment at each nitrogen site. Glycine-15N was converted to 2-chloroethylamine-15N hydrochloride (4 steps, 21% net yield) which was then reacted with phenyl dichlorophosphate to provide N,N′-bis(2-chloroethyl)phosphorodiamidic-15N2 acid phenyl ester [62%, PhOP(O) (15NHCH2CH2Cl)2]. Catalytic hydrogenation of this phenyl ester followed by the addition of cyclohexylamine (CHA) provided IPM-15N2 as the CHA salt (63%).
合成了伊福酰胺代谢物异磷酰胺芥子气(IPM),并在每个氮位点进行了同位素富集。甘氨酸-15N 转化为 2-氯乙胺-15N 盐酸盐(4 个步骤,净产率 21%),然后与二氯磷酸苯酯反应,得到 N,N′-双(2-氯乙基)磷二酰胺-15N2 酸苯酯[62%,PhOP(O) (15NHCH2CH2Cl)2]。对这种苯基酯进行催化氢化,然后加入环己胺 (CHA),得到了作为 CHA 盐的 IPM-15N2(63%)。
