4-Ethoxycarbonyl analogs of cyclophosphamide and its five-membered ring homolog were synthesized utilizing the cyclization method previously described. N,N-Bis(2-chloroethyl)-4-ethoxycarbonyl-1,3,2-oxazaphospholidin-2-amine 2-oxide demonstrated activity against L-1210 lymphoid leukemia whereas N,N-bis(2-chloroethyl)-4-(ethoxycarbonyl)tetrahydro-2H-1,3,2-oxazaphosphorin-2-amine 2-oxide did not. The
利用前述的环化方法合成了环磷酰胺的4-乙氧羰基类似物及其五元环同系物。N,N-双(2-氯乙基)-4-乙氧基羰基-1,3,2-氧杂磷腈-2-胺2-氧化物具有抗L-1210淋巴白血病的活性,而N,N-双(2-氯乙基)-4 -(乙氧羰基)四氢-2H-1,3,2-氧杂磷酰基-2-胺-2-氧化物没有。oxazaphosphorin-2-amine评估了人类鼻咽表皮样癌(细胞培养)。结果再次为负:ED50 = 2.8 X 10。
