Enantiopure five-membered ring nitrones derived from L-tartaric acid and from L-malic acid undergo highly regio- and stereoselective cycloaddition reactions with an excess of racemic 2,3-dihydro-1-phenyl-1H-phospholes producing two readily separable tricy
Stereoselective synthesis and resolution of P-chiral phosphine chalcogenides

New synthetic methods and resolution procedures securing ready access to the resolved P-chiral phosphinoylethenes, phosphinoylacetates and secondary phosphine oxides of diversified structures have been developed. The methods are based on processes employing stereoselective nucleophilic displacement at phosphorus, asymmetric deprotonation, immolative vinyl and chirality transfer from sulfur to phosphorus, chemical and enzymatic kinetic resolution, resolution via covalent diastereoisomers, as well as direct resolution of racemates by classical resolving agents and by chromatography on chiral stationary phases.
