The 10α,20β-bis(4-nitrophenyl)-calix[4]pyrrole was found to act as an effective organocatalyst for the hetero Diels-Alder reaction of Danishefsky's diene with aromatic aldehydes. This discovery is the first reported case of a calixpyrrole that exhibits or
Tuning the anion binding properties of calixpyrroles by means of p-nitrophenyl substituents at their meso-positions
Bruno, Giuseppe,Cafeo, Grazia,Kohnke, Franz H.,Nicolò, Francesco
, p. 10003 - 10010 (2007)
Extended cavity calix[4]pyrroles and a calix[6]pyrrole were synthesized by cyclization of 5-methyl-5-(4-nitrophenyl)dipyrromethane with acetone in the presence of acid. The solid-state structures of the novel macrocycles were determined by X-ray crystallo
A catalytic and solvent-free approach for the synthesis of diverse functionalized dipyrromethanes (DPMs) and calix[4]pyrroles (C4Ps)

Needless to say, the development of green and sustainable reaction media instead of using volatile organic solvents as well as corrosive and/or expensive catalysts in the new millennium is continuously attracting great attention from the scientific commun
Thermodynamic characterization of halide-π interactions in solution using "two-wall" aryl extended calix[4]pyrroles as model system
Adriaenssens, Louis,Gil-Ramirez, Guzman,Frontera, Antonio,Quinonero, David,Escudero-Adan, Eduardo C.,Ballester, Pablo

Herein, we report our latest experimental investigations of halide-π interactions in solution. We base this research on the thermodynamic characterization of a series of 1:1 complexes formed between halides (Cl -, Br-, and I-/s
Quantification of nitrate-π interactions and selective transport of nitrate using calix[4]pyrroles with two aromatic walls
Adriaenssens, Louis,Estarellas, Carolina,Vargas Jentzsch, Andreas,Martinez Belmonte, Marta,Matile, Stefan,Ballester, Pablo
supporting information, p. 8324 - 8330 (2013/07/11)
Herein we disclose the results of our investigations regarding the interactions between the biologically relevant nitrate oxoanion and several "two-wall" aryl-extended calix[4]pyrroles. There exists a clear relationship between the electronic nature of th
