The dynamickineticresolution of α-keto esters via asymmetric transfer hydrogenation has been developed as a technique for the highly stereoselective construction of structurally diverse β-substituted-α-hydroxy carboxylic acid derivatives. Through the development of a privileged m-terphenylsulfonamide for (arene)RuCl(monosulfonamide) complexes with a high affinity for selective α-keto ester reduction

The condensation of an .alpha.-halogen carbonyl compound with carbamic acid esters in the presence of a basic condensing agent and an aprotic solvent enables the production of oxazolinone-2-compounds in a high degree of purity, and in high yields in one step by using simple and readily available starting compounds.
