Oxa Calixarene And Its Derivatives, And Nature Study

The ordinary calixarene is the macrocyclic compounds which formed by many 2,5-phenol connected through the methyl. It is the third generation supramolecular after the cyclodetrin and the crown ether,which has not only the merit of cyclodetrin and crown ether, but also easier derivation . In order to obtain more structures unique, performance outstanding calixarene. Calixarene expand to the mixed oxygen,mixed nitrogen,mixed sulfur calixarene at the ordinary calixarene foundation, Oxacalix[n]arene is a important kind among these calixarene.This article embarked from supramolecular view and designed the synthesis of hexahomooxacalix[3]arene from originally material. Two novel Capped-hexahomooxacalix[3]arene were synthesized at the base of hexahomooxacalix[3]arene that was many stepps derivatied. The structure of these hexahomooxacalix[3]arene derivations was analysised by the IR,~1H NMR and X—ray.we had discovered one kind extremely way to fix the configuration of calixarene when we studied several way to synthesis Capped-hexahomooxacalix[3]arene from different configuration material. and studied the performance of complexing halogenion. We successful synthesised Capped-hexahomooxacalix[3]arene ester when we little synthesized. But when we repetition syntheised we suddenly got hexahomooxacalix[3]arene triaceticester.It is very significance to synthesis the short arm chain derivation of Oxacalixarene. It has enormous enriched the synthesis way of Cone-Oxacalixarene derivative.
