几种杯[4]二酰胺化合物的合成及其对某些离子的络合作用

The Synthesis of A Few p-t-butycalix arene Diamides and Its Complexation with Some Ions

通过在杯 [4 ]芳烃下沿进行修饰 ,在叔丁基杯 [4 ]芳烃上加溴乙酸乙酯得 2 5 ,2 7-双乙氧羰基甲氧基 -2 6,2 8-二 -羟基杯 [4 ],然后在碱性条件下水解 ,且酰氯化 ,再依次酰胺化 ,制得目标分子 Va～ Vc.采用分子光谱法 ,测定了这些酰胺对一些离子的络合效应 .

The calix arene was modified in the lower rim.At first we get the 25,27-bisethoxycarbhonylmethoxy1-26,28-dihydroxyl-calix arene through adding ethyl bromoacetate to t-buty-calix arene.Then hydrolyzation under basic condition and chloride acylation and acylmidation go on in turns,so at last we synthesize targe molecule V a^V c and by comparison of these host molecule's complex effect to ions.
