A series of α-amino (2, or 4)-fluorobenzyl-phosphonates containing isoxazole moiety were synthesized by the reaction of fluorobenzoaldehyde, 3-amino-5-methylisoxazole and dialkyl phosphite under unltrasound irradiation without solvent and catalyst. Their structures were established by elemental analysis, IR, 1H NMR and 13C NMR. The bioassay tests showed that these title compounds exhibit moderate anticancer
在不使用溶剂和催化剂的情况下,在超声辐射下,通过氟苯甲醛,3-氨基-5-甲基异恶唑和亚磷酸二烷基酯的反应,合成了一系列含有异恶唑基团的α-氨基(2或4)-氟苄基膦酸酯。通过元素分析,IR,1 H NMR和13 C NMR建立了它们的结构。生物测定测试表明,通过MTT方法,这些标题化合物在体外表现出中等的抗癌活性。4c的晶体结构已经通过X射线衍射确定。它在单斜晶系空间群P 2(1)/ n中结晶,单位晶胞参数为:a = 0.9335(3),b = 1.3067(4),c = 1.6552(6)nm,β = 104.801(6)°,Z = 4,V = 1.9521(11)nm 3,D c = 1.260 g / cm 3,μ = 0.172 mm -1,F(000)= 784通过直接方法求解晶体结构,并用全矩阵最小二乘法将其最终值R = 0.0524和wRwR = 0.1592,反射9902(I
