For the first time, an efficient method has been developed by the use of imidazolium ion tethered TsDPENs as efficient ligands for Iridium-catalyzed asymmetric transfer hydrogenation (ATH) of α-ketophosphonates in water. The reaction provided the desired
Enzymes in organic chemistry - 5: First and chemo-enzymatic synthesis of α-aminooxyphosphonic acids of high enantiomeric excess

α-Acyloxyphosphonates (±)-5a and (±)-5b, derived from 3-phenylpropionaldehyde and acetaldehyde, were resolved by lipase-catalyzed enantioselective hydrolysis. Three of the four chiral, non-racemic α-hydroxyphosphonates obtained had 99% ee, the fourth 91%.
Asymmetric Synthesis of Chiral, Nonracemic Dialkyl α-Hydroxyarylmethyl- and α-, β- and γ-Hydroxyalkylphosphonates from Keto Phosphonates
Meier, Chris,Laux, Wolfgang H. G.,Bats, Jan W.
, p. 1963 - 1980 (2007/10/03)
The enantioselective synthesis of α-hydroxyarylmethylphosphonates 2a-p by the oxazaborolidine-catalyzed reduction of α-keto phosphonates 1a-p using different boranes 4a-c was studied in detail.Moderate to good enantioselectivities are found (up to 80perce
