Selective mono-dealkylation of tetra-p-tert-butyl-calix[4]arene at the upper rim

The tris-p-(tert-butyl)calix[4]arene has been synthesized by a reproducible selective esterification-dealkylation-saponification process.

Azocalixarenes.7: Synthesis and study of the absorption properties of novel mono-azo substituted chromogenic calix[4]arenes

Eight new mono-azo substituted chromogenic calix[4]arenes (1-8) were synthesized by diazo-coupling reactions in which 25,26,27-tribenzoyloxy-28- hydroxy-5,11,17-tri-(tert-butyl)calix[4]arene and diazonium salts (2-, 3-, and 4-nitroaniline; 4-phenyl azoani

Synthesis and characterization of imidazole-substituted calix[4]arenes as simple enzyme-mimics with acyltransferase activity

Calix[4]arenes which bear imidazole groups at different positions at the wide rim act as catalysts for enzyme-like release of p-nitrophenol from p-nitrophenyl esters in buffered solution.
