## Abstract We first make use of aminolysis of calix[4]arene esters to synthesize calix[4]arene amides. When the two ethyl esters of the calix[4]arene esters are aminolysized, the 1, 3โamide derivative is formed selectively. The crystal structures of the calixโ[4] arene with two butyl amide (3b) an
## Abstract Four __pโtert__โbutylcalix[4]arene derivatives with different Schiff base groups at the lower rim were efficiently prepared in three steps. __pโtert__โButylcalix[4]arene was firstly __Oโ__peralkylated with __ฯ__โhaloalkylphthalimide in the system of NaH/DMF to give calixarene tetraalkyl
