rolidine (RAMP)-hydrazone method, are oxidized to give α-hydroxy-ketones (R)−5 of high enantiomeric purity (ee ≥ 98%) and in good overall yields (51-70%). The key step of the procedure is the silicon-directed diastereoselective oxidation of the corresponding silyl enol ethers of (S)−2, with m-chloroperbenzoic acid or 3-phenyl-2-(phenylsulfonyl)oxaziridine, followed by flash chromatography and desilylation
