Stereoselective Syntheses of Organophosphorus Compounds

Symmetry
The review is devoted to the theoretical and synthetic aspects of the stereochemistry of organophosphorus compounds. Organophosphorus compounds are not only widely exist in biologically active pharmaceuticals and agrochemicals, but also have widespread applications in material science and organic synthesis as ligands for transition metal complexes.

Zero-field NMR J-Spectroscopy of Organophosphorus Compounds [PDF]

, 2020
In this paper, we report the results of theoretical and experimental studies on basic organophosphorus compounds using zero-field NMR, where spin dynamics are investigated in the absence of a magnetic field with the dominant heteronuclear J-coupling. We

Organocatalytic asymmetric synthesis of P-stereogenic molecules

Frontiers in Chemistry, 2023
P-chirality broadly appears in natural and synthetic functional molecules. The catalytic synthesis of organophosphorus compounds bearing P-stereogenic centers is still challenging, due to the lack of efficient catalytic systems.
