    • A representative procedure is as follows: Prepartion of 2-nitro-1,3-diols 2:To a solution of potassium carbonate (276 mg, 2 mmol) in 5 ml of water, formaldehyde (0.233 ml of 30% water solution, 3 mmol) and 2-nitrocycloalkanone (1 mmol) were added. After stirring overnight at room temperature (50°C for the preparation of 2i) 10 ml of water was added, the solution was acidified with 10% hydrochloric acid and extracted with EtOAc (5 × 10 ml). The organic layer was dried over sodium sulfate, filtered and evaporated under reduced pressure to leave a crude product which was purified by reversed-phase chromatography (sometimes yields decreased owing to partial decomposition of nitrodiols on LiChroprep).
