, p. 2848 - 2852 (2004)
A simple and direct protocol is reported for the synthesis of the first non-symmetrically substituted 1,3-alternate conformers of calix[4]arenes by selective mono-deacylation of a tribenzoyl precursor under basic conditions, followed by dialkylation. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
Unexpected Single-Step Formation of 1,2-anti-Heterodisubstituted Calix[4]arenes upon Alkylation of a Tribenzoyl Precursor

The selective preparation and complete structural characterization of a small series of 1,2-anti-hetero-disubstituted calix[4]arenes has been accomplished. These compounds were obtained in two steps from unsubstituted p-tert-butylcalix[4]arene by tribenzo
Synthesis and characterization of imidazole-substituted calix[4]arenes as simple enzyme-mimics with acyltransferase activity
Dospil, Günter,Schatz, Jürgen
, p. 7837 - 7840 (2007/10/03)
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.
