bis-thiophosphoryl disulfides under kinetic resolution conditions (2:1 ratio) afforded enantiomerically enriched tertiary phosphine oxides or phosphine sulfides with ee values up to 39%. In a similar way from racemic tert-butylphenylchlorophosphine, opticallyactive tert-butylphenylphosphinoyl chloride with 50% ee was obtained. The same reaction performed under dynamic kinetic resolution conditions (1:1 ratio
Enantiomerically pure disulfides were reacted with various chiral P-III-derivatives with stereogenic phosphorus such as tertiary phosphines, halogenophosphines, phosphinite and phosphole under kinetic resolution conditions to afford enantiomerically enriched phosphine oxides or sulfides with ee values up to 50%. Enantiomeric excess rose to 70% under dynamic kinetic resolution-conditions in the case of tert-butylphenylchlorophosphine. (C) 2004 Elsevier Ltd. All rights reserved.

Phosphorous Incorporation (PI, abbreviated Π) reagents for the modular, scalable, and stereospecific synthesis of chiral phosphines and methyl-phosphonate nucleotides are reported. Synthesized from trans-limonene oxide, this reagent class displays an unexpected reactivity profile and enables access to chemical space distinct from that of the Phosphorous-Sulfur Incorporation reagents previously disclosed

and H-phosphine oxides was reported. H-Phosphinates and H-phosphine oxides react stereospecifically with CuCl2 to produce the corresponding optically active Z1Z2P(O)Cl with retention of configuration at the phosphorus center. Optically active Z1Z2P(O)Cl reacts easily with a variety of nucleophiles to produce other chiral organophosphorus acid derivatives with inversion of configuration at phosphorus
