Stereoselective Chiral Recognition of Amino Alcohols with 2,2′-Dihydroxybenzil

2,2′-Dihydroxybenzil is demonstrated to be a highly diastereoselective stereodynamic receptor for the chiral recognition of amino alcohols. The receptor by forming diimine compounds with amino alcohols showed good (11:1) to excellent (>50:1) diastereoselectivity in chloroform. The existence of intramolecular hydrogen bonding with amino alcohols only in an axial conformer is demonstrated by 1H NMR and CD spectroscopy, X-ray crystallography, and DFT computations. The exciton chirality method can be used with diazo-attached 2,2′-dihydroxybenzil.

2,2′-dihydroxybenzil: A stereodynamic probe for primary amines controlled by steric strain

A rational approach for generating 1,1′-binaphthalene-like axial chirality of a small organic receptor, 2,2′-dihydroxybenzil is presented. The receptor combines with 2 equiv of monodentate primary amines to form a diimine, of which axial chirality is controlled by steric strain with moderate (1.4:1) to good (4.7:1) stereoselectivity. The observed circular dichroism (CD) spectra have been closely simulated by TD-DFT computations and can be used for determining the absolute chirality and enantiomeric excess of primary amines.

Highly selective recognition of fluoride anion through direct deprotonation of intramolecularly hydrogen-bonded phenolic hydroxyl groups

A novel chemosensor for fluoride anion has been developed. This sensor, constructed by merging six phenolyl units into a hexaazatriphenylene (HAT) core, could recognize F- visually and spectroscopically with high selectivity over other anions,
