Synthesis and enantiomeric recognition studies of optically active 5,5-dioxophenothiazine bis(urea) and bis(thiourea) derivatives

Novel optically active 5,5-dioxophenothiazine bis(urea) and bis(thiourea) derivatives were synthesized and their enantiomeric recognition abilities toward the enantiomers of tetrabutylammonium salts of α-hydroxy and N-protected α-amino acids were examined in acetonitrile using fluorescence spectroscopy.

Synthesis and enantiomeric recognition studies of optically active acridone bis(urea) and bis(thiourea) derivatives

Novel optically active acridone bis(urea) and bis(thiourea) derivatives were synthesized and their enantiomeric recognition abilities towards the enantiomers of tetrabutylammonium salts of α-hydroxy and N-protected α-amino acids were examined in acetonitrile-DMSO 99:1 using fluorescence spectroscopy.

Synthesis and enantiomeric recognition studies of a novel 5,5-dioxophenothiazine-1,9 bis(thiourea) containing glucopyranosyl groups

A novel optically active 5,5-dioxophenothiazine-1,9 bis(thiourea) containing glucopyranosyl groups was synthesized and its enantiomeric recognition properties were examined towards the enantiomers of tetrabutylammonium salts of chiral α-hydroxy and N-protected α-amino acids using UV-vis spectroscopy.

Influence of the size and geometry of the anion binding pocket of sugar-urea anion receptors on chiral recognition

Three new chiral urea-type anion receptors were synthesized from aromatic diamines and 1-amino-1-deoxyglucose. The anion binding properties of these receptors were studied using chiral carboxylates derived from mandelic acid and three α-amino acids. We found that the size of the anion binding pocket played an important role in chiral recognition processes. The best results were obtained for 1,8-diaminoanthracene and α-amino acid anions.

Sweet anion receptors: Recognition of chiral carboxylate anions by d-glucuronic-acid-decorated diindolylmethane

Anion receptors containing glucuronic acid were synthesized, and their anion binding ability studied. Chirality of anionic guests derived from mandelic acid and amino acids can be distinguished not only in terms of stability constants but also by signific

Novel chiral fluorescent macrocyclic receptors: synthesis and recognition for amino acid anions

New chiral fluorescence macrocycles 1 and 2 containing naphthalene and amino acid units were synthesized. The binding properties for amino acid anions were examined by the fluorescence and 1H NMR spectra. The results indicated good enantioselec

ONE-POT CYCLIZATION OF A PEPTIDE BY THE USE OF (5-NITROPYRIDYL)DIPHENYL PHOSPHINATE: THE SYNTHESIS OF CYCLIC DECAPEPTIDE GRAMICIDIN S

One-pot synthesis of gramicidin S, cyclic decapeptide, was successfully achieved by treatment of the corresponding linear decapeptide with (5-nitropyridyl)diphenyl phosphinate, a new condensing reagent, in pyridine.Similarly, the phosphinic ester can be successfully employed in the Young test as well as syntheses of dipeptides.
