Aroyl group driven phosphonate-phosphate rearrangement in dialkyl/aryl(α-hydroxy-β-oxo-β-arylethyl)phosphonates having α-proton under basic conditions is presented and extended to a novel one-pot direct coupling method between 2-oxoaldehydes (2OA) and H-p

Dynamic kinetic resolution driven, asymmetric transfer hydrogenation of 4-substituted cyclic sulfamidate imine-5-phosphonates produces the corresponding cyclic sulfamidate-5-phosphonates. The process employs a HCO2H/Et3N mixture as the hydrogen source and the chiral Rh catalysts, (R,R)- or (S,S)-Cp?RhCl(TsDPEN), and it takes place at room temperature within 1 h with high yields and high levels of stereoselectivity.

Highly efficient catalyst free methods for the synthesis of α-hydroxy-β-oxophosphonates and α-oxoesters have been described. The existence of a 2-oxo group in α-oxoaldehydes is a key factor in promoting the reaction of the tervalent phosphite form towards 2-oxoaldehydes in the synthesis of α-hydroxy-β-oxophosphonates. The in situ activated α-C-H atom of α-hydroxy-β-oxophosphonates sustains aerobic intramolecular nucleophilic displacement in a curious way to produce α-oxoester.
