The calixarenic receptors exhibit remarkable host–guest properties towards biologically
relevant guests. Aspects of complex formation reactions between both native and …

Chirality recognition of pharmaceutical products plays a significant part in asymmetric
synthesis, stereoselective catalysis, supramolecular chemistry, and the development of new …

The synthesis of the first calixarene-based chiral phase-transfer catalysts derived from
cinchona alkaloids has been achieved in two steps from p-tert-butylcalix [4] arene. The …

In this study the synthesis of novel chiral calix [4] azacrown derivatives has been reported.
The enantioselectivity of chiral receptors was investigated by using UV–vis spectroscopy. All …

Two armed chiral calix [4] arenes 8–16 functionalized at the lower rim with chiral
aminonaphthol units have been prepared and the structures of these receptors …

This chapter will focus on the use of chiral solvating agents (CSAs) for the detection and
quantification of enantiomeric substrates by nuclear magnetic resonance spectroscopy, with …

Four optically active amino alcohols were synthesized via the ring opening of (R)-N-(2, 3-
epoxypropyl) phthalimide with (R)-2-phenyl glycinol,(1R, 2S)-cis-1-amino-2-indanol,(R)-2 …

Calixarenes, obtained in the condensation reaction of formaldehyde and p-substituted
phenols, are often referred to as the third generation of supramolecular receptors after crown …

Abstract Calixarenes (CAs) and calix [4] resorcinarenes are cavity compounds, chiral
analogues of which have the potential to be used as reagents for the differentiation of …

Enantiopure diphenylprolinols were synthesized from a commercially available starting
material. The utility of 1H NMR spectroscopy for the differentiation of enantiomers using …
