Synthesis and binding behavior of an artificial receptor based on “upper rim” functionalized calix[5]arene
摘要:
A new calix[5]arene possessing two benzoic acid moieties was synthesized as an artificial receptor and its ability of binding to a variety of amine guests was investigated. The structures of the complexes with the amines were proposed by the molecular mechanics calculation using MacroModel V. 4.0. (C) 1998 Elsevier Science Ltd. All rights reserved.

Calix[4]arenes with three different substituents in ABAC pattern at the upper rim of calix are synthesized by '3 + 1' fragmentation condensation reaction between trimer of p-substitutedphenol (ABA) and 2.6-bishydroxymethylated p-substitutedphenol (C).

Four calix[5]arenes, which have three different substituents at the upper rim of calix, are synthesized by the ‘3+2’ fragmentation condensation reaction. An equimolar mixture of p-substituted phenol trimer (BCB) and 2,2’-bishydroxymethyl p-substituted phenol dimer (AA) was refluxed for 3.5 days in xylene to produce calix[5]arenes 5a-d in 27-32% isolated yield. The structure of the calix[5]arenes was established by elemental analysis and 1H NMR/13C NMR spectroscopy.

stencal hindered compounds 2a-f up to 315°C leads to the corresponding bicyclicphosphites 3a-d while the non-hindered phosphocins 2g-i react in refluxing xylene to give phosphites 3e-g. The phosphocin 2i formed another phosphocin 2i* during heating to 90°C in THF by “wandering” of the phosphorus moiety. The bicyclicphosphites 3h and 3i were prepared starting from tetraphenol 1h and pentaphenol 1i

A new carix[5]arene possessing two benzoic acid moieties was synthesized as an artificial receptor, and its ability of binding for imidazole was investigated. The carix[5]arene forms a cone shaped cavity, in which two imidazolium ions were included. The structure of the complex with two imidazolium ions was proposed by using Monte-Carlo-AMBER* simulation in Macro Model V. 4.0.
