New cyclophosphamide derivatives having the 1, 3, 4, 2-oxadiazaphosphorinane and related heterocyclic systems were prepared by the ozonolysis reactions of O-(2-propenyl)-and O-(3-butenyl)-N, N-bis(2-chloroethyl) phosphoramidoyl hydrazides and their derivatives. The newly synthesized heterocyclic systems were dihydro-6H-1, 3, 4, 2-oxadiazaphos-phorine-2-oxide, 4-acetyl-5-hydroxy-1, 3, 4, 2-oxadiazaphosphorinane-2-oxide, 4-acetyl-5-hydroxyhexahydro-2H-1, 3, 4, 2-oxadiazaphosphepine-2-oxide and perhydro-1, 3, 4-oxadiazolo [3, 2-c]-1, 3, 2-oxazaphosphorine-1-oxide. Comparative studies of the in vivo antileukemic activity revealed that these cyclophosphamide derivatives were ineffective in promoting the antitumor action.
通过O-(2-丙烯基)-和O-(3-丁烯基)-N,N-双(2-氯乙基)膦酰胺基酰肼及其衍生物的臭氧分解反应,制备了具有1,3,4,2-氧二氮杂磷杂环己烷及相关杂环系统的新型环磷酰胺衍生物。新合成的杂环系统包括二氢-6H-1,3,4,2-氧二氮杂磷杂环己烷-2-氧化物、4-乙酰基-5-羟基-1,3,4,2-氧二氮杂磷杂环己烷-2-氧化物、4-乙酰基-5-羟基六氢-2H-1,3,4,2-氧二氮杂磷杂环己烷-2-氧化物及全氢-1,3,4-氧二氮杂[3,2-c]-1,3,2-氧氮杂磷杂环己烷-1-氧化物。体内抗白血病活性比较研究表明,这些环磷酰胺衍生物在促进抗肿瘤作用方面无效。
