Preparation of Methylene-Substituted Calixarenes, methods include the cyclization of fragments, the homologous anionic . Fries rearrangement, the spirodienone method, the lithiation/alkylation approach, the oxidation of the bridges followed by reaction of the carbonyl units with organolithium reagents, and the bromination of the bridges followed b

Large Calixarenes, “large” calixarenes. In particular, their synthesis, chemical modification, and supramolecular properties are here reviewed. Notwithstanding their unfavorable common features (the lack of efficient large-scale syntheses, an intricate chemistry, a high conformational mobility, which imply many possi

Calixarenes and Resorcinarenes Bridged at the Wider Rim,tline some of the strategies used and provide a flavour of the range of linking groups investigated. Bridging calixarenes with four equivalent rings usually results in a mixture of predominantly mono- and di-proximally bridged derivatives. For the synthesis of distally bridged calixarenes, a selecti
