applied on tetrakis[p‐(halogenomethyl)]‐ and tetrakis[p‐(aminomethyl)]calix[4]arene derivatives to improve the synthesis of the 5,11,17,23‐tetrakis[(diethylphosphono)methyl]‐25,26,27,28‐tetrahydroxycalix[4]arene. Two new, high yield, synthetic pathways have been selected, involving, for the first one, the 25,26,27,28‐tetrahydroxy‐5,11,17,23‐tetrakis[(trimethylamino)methyl]calix[4]arene, tetraiodide
四[对-(卤代甲基)]和四[对-(氨基甲基)]杯[4]芳烃衍生物已应用了各种操作条件,以改善5,11,17,23-四[[二乙基膦酰基)的合成甲基] -25,26,27,28-四羟基杯[4]芳烃。选择了两个新的高产合成途径,第一个涉及25,26,27,28-四羟基-5,11,17,23-四[[三甲基氨基)甲基]杯[4]芳烃,四碘化物,DMF和10当量。亚磷酸三乙酯((EtO)3 P),而另一种是5,11,17,23-四(溴甲基)-25,26,27,28-四羟基杯[4]芳烃,CH 2 Cl 2,并且只有4个当量。(ETO)的2 P.
