  Synthesis of and amine recognition with a Cu(II)-bridged biscalix[4]arene

  摘要：

  A biscalix[4]arene (7) in which the upper rims are linked by two Cu(II)-chelate complexes has been synthesized. This is a novel method for the synthesis of biscalix[4]arenes using the self-association nature of metal ligands. Compound 7 recognized diamine substrates using a cavity composed of two Cu(II)-chelate complexes.

  Tetra-O-alkylated calix[4]arenes in the 1,3-alternate conformation

  摘要：

  A general method has been developed for the preparation f tetra-O-alkylated calix[4]arenes in the 1,3-alternate conformation (3a,c-e) starting from p-tert-butylcalix[4]arenes 1a,b using Cs2CO3 in DMF. The 1,3-alternate conformation was unequivocally proved by an X-ray structure determination of 3a. The scope of the reaction was investigated starting from a series of diametrically di-O-alkylated calix[4]arenes 4a-e having different substituents R2 (t-Bu, CHO, NO2, Br, CN) at the para positions of the phenolic rings. The reactions of 4a-d (R2 = t-Bu, CHO, NO2, Br) yielded the corresponding tetra-0-alkylated calix[4]arenes in the 1,3-alternate conformation 5a-d (51-73%). However, the dicyanocalix[4]arene 4e gave the partial cone conformer 6 as the major reaction product.
