, p. 1089 - 1092 (1995)
A highly enantioselective synthesis of dialkyl α-hydroxyphosphonates achieved by a oxazaborolidine catalyzed reduction with catecholborane starting with α-ketophosphonates is described.Both α-aryl- and α-alkylketophosphonates were reduced using the (S)-en

Asymmetric phosphonylation of aldehydes with trialkyl phosphites using a combination of SiCl4 and a novel 1,1′-dibenzyl-bis-(triazolyl)diphenylphosphine dioxide organocatalyst has been developed. This protocol provides the corresponding α-hydroxyphosphonates with a broad range of functional groups and substitution patterns in excellent yields and good selectivities.
Imidazolium ion tethered TsDPENs as efficient ligands for Iridium catalyzed asymmetric transfer hydrogenation of α-keto phosphonates in water

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
