Rapid and efficient synthesis of unsymmetrical phosphinic acids r′t(o)ohr″
Fougere, Cecile,Guenin, Erwann,Hardouin, Julie,Lecouvey, Marc
experimental part, p. 6048 - 6054 (2010/03/02)
A new synthesis of unsymmetrical phosphinic acids R′P(O)OHR″ has been evaluated, The first P-C bond was formed by base-promoted H-phosphinate alkylation of a protected H-phosphinate, which is easier and safer to handle, A onepot methodology was developed for the second P-C bond formation reaction that: involves the sila-Arbuzov reaction. This methodology was then extended to the synthesis of a dialkylphosphinic acid with an amino functionality.
Efficient synthesis of mono- and diarylphosphinic acids: a microwave-assisted palladium-catalyzed cross-coupling of aryl halides with phosphinate
Kalek, Marcin,Stawinski, Jacek
experimental part, p. 10406 - 10412 (2010/02/27)
A general, efficient method for the microwave-assisted synthesis of mono- and diarylphosphinic acids from anilinium phosphinate and aryl halides, using Pd(0) and Xantphos as a supporting ligand, was developed.
Green, palladium-catalyzed synthesis of benzylic H-phosphinates from hypophosphorous acid and benzylic alcohols
Coudray, Laetitia,Montchamp, Jean-Luc
supporting information; experimental part, p. 4101 - 4103 (2009/05/07)
Benzylic alcohols cross-couple directly with concentrated H 3PO2 by using Pd/xantphos (1 or 2 mol-%). Depending on the substrate, DMF at 110 °C or t-AmOH at reflux with a Dean-Stark trap can be used. A broad range of benzylic alcohols react successfully to give moderate to good yields of the products. The preparation of other organophosphorus compounds (phosphinic and phosphonic acids) is also demonstrated. Asymmetric reaction with (R)-1-(2-naphthyl)-ethanol provids the corresponding H-phosphinic acid in 77% ee. The methodology provides a green, PCl3-free route to benzylic-H-phosphinic acids.

Recent advances in phosphorus-carbon bond formation: Synthesis of H-phosphinic acid derivatives from hypophosphorous compounds
Montchamp, Jean-Luc
, p. 2388 - 2406 (2007/10/03)
This account summarizes the research conducted in our laboratory over the past five years. New methodologies were devised for the formation of P-C bonds with a focus on the reactions of hypophosphorous acid derivatives. Three types of reactions have been developed: palladium-catalyzed cross-coupling, room-temperature radical addition, and palladium-catalyzed addition. Our results are summarized in each of these areas and include some of our most recent data. (1) Our palladium-catalyzed cross-coupling has been extended to the direct coupling of alkyl phosphinates with a variety of aryl, heteroaryl, and even alkenyl electrophiles. (2) The addition of sodium hypophosphite under radical conditions is extended from alkenes to alkynes. (3) The catalytic addition of hypophosphorous compounds using palladium catalysts (hydrophosphinylation) is also discussed.

Design and pharmacological activity of phosphinic acid based NAALADase inhibitors
Jackson,Tays,Maclin,Ko,Li,Vitharana,Tsukamoto,Stoermer,Lu,Wozniak,Slusher
, p. 4170 - 4175 (2007/10/03)
A novel series of phosphinic acid based inhibitors of the neuropeptidase NAALADase are described in this work. This series of compounds is the most potent series of inhibitors of the enzyme described to date. In addition, we have shown that these compounds are protective in animal models of neurodegeneration. Compound 34 significantly prevented neurodegeneration in a middle cerebral artery occlusion model of cerebral ischemia. In addition, in the chronic constrictive model of neuropathic pain, compound 34 significantly attenuated the hypersensitivity observed with saline-treated animals. These data suggest that NAALADase inhibition may provide a new approach for the treatment of both neurodegenerative disorders and peripheral neuropathies.
