The diastereoselective synthesis of “pre-activated” analogues of cyclophosphamide in the 3-[bis(2-chloroethyl)amino]-2-aza-4,9-dioxa-3-phosphabicyclo(4.3.0)nonane 3-oxide series in described, using either the phosphorylation of an azidoalcohol followed by a reductive cyclisation or the phosphorylation of an acetal alcohol followed by an unprecedent direct Lewis acid catalyzed intramolecular substitution
非对映选择性合成3- [双(2-氯乙基)氨基] -2-氮杂-4,9-二氧杂-3-磷杂双环(4.3.0)壬烷3-氧化物系列中环磷酰胺的“预活化”类似物所述的方法是使用叠氮醇的磷酸化,然后进行还原性环化,或者使用乙醛醇的磷酸化,然后进行前所未有的直接路易斯酸催化的分子内取代。
