R ‐ or S ‐configured 1,2‐diol precursors are formed in good yields (54–86 %) and with excellent enantioselectivities (94 to 99 % ee ) by using a simple one‐pot sequence—catalytic α‐aminoxylation of aldehydes followed by in situ reduction with NaBH 4 —with L ‐ or D ‐proline as the catalyst and nitrosobenzene as the oxygen source (see scheme).
