Conjugates of calixarenes emerging as molecular entities of nanoscience
, 2012 Calixarenes, along with cyclodextrins (viz. β-CD) and crown ethers, are the most commonly studied macrocyclic compounds. These bucket shaped molecules have gained tremendous importance for having both hydrophilic and hydrophobic compartments together in ...

Efficient Synthesis of Water-Soluble Calixarenes Using Click Chemistry
, 2016 Several water-soluble calix[4]arenes were synthesized via Huisgen 1,3-dipolar cycloaddition between azides and alkynes. Cationic, anionic, and nonionic calixarenes were prepared from a common azidocalixarene intermediate.

Synthesis of N-phtaloyl amino acid p-tert-butylcalix[4]arene esters
Journal of the Brazilian Chemical Society, 2001 1-3-Diesters of p-tert-butylcalix[4]arene were obtained upon reaction with N-phtaloyl amino acid chlorides. Reactions with chiral amino acids were accompanied by complete or partial racemization in the reaction media (Et3N/CH2Cl2).

Naphthalene-Based Calixarenes: Unusual Regiochemistry of a Friedel−Crafts Alkylation
, 2016 In the pursuit of naphthalene-based calixarenes, a Friedel−Crafts alkylation with unusual regiochemistry was observed. Treatment of carbinol 14 with catalytic triflic acid was expected to produce calixarenes of the class represented by 16.

Calixarenes in Lipase Biocatalysis and Cancer Therapy
, 2016 Calixarenes are supramolecular structures characterized by their "calix" shape and their easy synthetic accessibility. They are amphiphilic in nature, thus they can bear in their structure both hydrophobic and hydrophilic features as well as charged ...
