Full Title: Synthesis and Characterization of New bis-Symmetrical Adipoyl, Terepthaloyl, Chiral Diimido-di-L-alanine Diesters and Chiral Phthaloyl-L-alanine Ester of Tripropoxy p-tert-Butyl Calixarene and Study of Their Hosting Ability for Alanine and Na+
Bis-symmetrical tripropoxy p-tert-butyl calixarene esters were prepared from the reaction of tripropoxy calixarene (1HPr3) with di-acyl chlorides as bridges in the presence of sodium hydride. The esters, which were synthesized from L-alanine acyl chloride derivatives, are optically active. In all of these esters, calixarene cavities have a pinched cone conformation. The structures of these esters were confirmed by FT-IR, 1HNMRand 13CNMRspectroscopy, elemental analysis and ion positive FAB mass spectrometry.
