α-Hydroxyacids can be enantioselectively prepared by means of a two-step oxidation process, involving first the asymmetric dihydroxylation of a terminal alkene and subsequent oxidation with TEMPO/NaOCl/NaClO 2 in good to excellent yields. No fragmentation of the glycol intermediate was detected.

Enantioselective Synthesis of α-Hydroxy Phosphonates via Oxidation with (Camphorsulfonyl)oxaziridines. -Chiral dichloro oxaziridines (OXA) are used for the enantioselective introduction of the hydroxy group to prochiral phosphonates. The (+)-reagent favors the formation of (S)-products. Phosphonate
