Binding properties of an abiotic receptor for complexing carboxylates of α-heterocyclic and α-keto acids
摘要:
A receptor with high molecular recognition of carboxylates of alpha -heterocyclic and alpha -keto acids was prepared by introduction of hydroxamic function in a neutral anion binding receptor with a framework of bis-chromenylurea. The improved complexation of the host toward these guests resulted from a fifth hydrogen bond in the complexes between the OH donor of the host and the alpha -heteroatom acceptor of the guests.
