Comprehensive conformational study of key interactions involved in zearalenone complexation with beta-D-glucans.
The beta-D-glucans from the cell wall of Saccharomyces cerevisiae have shown in vitro affinity for zearalenone. For this reason, their utilization as dietary adsorbent, to reduce the bioavailabilityExpand

Determination of absolute configurations of amines and amino acids using nonchiral derivatizing agents (NCDA) and deuterium NMR.
Enantiomeric analysis and empirical determination of the absolute configuration of amines and amino acids can be easily performed using acetyl-d(3) chloride as a nonchiral derivatizing agentExpand

Enantioselective synthesis of (−)-indolizidine 167B
Abstract The enantioselective total synthesis of (−)-indolizidine 167B is described. The key step is the intramolecular cyclization of the chiral N -acyliminium ion 6 . Indolizidine 167B was obtainedExpand

Visualization of enantiomers through deuterium NMR in cholesterics. Optimization of the chiral liquid crystal solvent
Abstract Thermotropic cholesteric liquid crystals made of mixtures of cholesteric esters and of a Δχ <0 nematic (ZLI2806) may be used as NMR solvents to visualize enantiomers. Proton decoupledExpand

Acetyl-d(3) Chloride: A Convenient Nonchiral Derivatizing Agent (NCDA) for a Facile Enantiomeric Excess Determination of Amines through Deuterium NMR.
Different methods have been proposed for the determination of the enantiomeric purity of chiral amines by NMR.1 These methods are mainly based on the use of chiral auxiliaries which react withExpand
