    • General procedure for the synthesis of β-hydroxynitroalkane compounds. A mixture of aldehydes 1 (2.0 mmol, nitroalkane 2 (5.0 mmol) was stirred in [bmIm]OH (20 mol, at room temperature for 1-8 h. The reactions were monitored by TLC. Upon and on completion, the products were extracted with ethyl acetate, dried with anhydrous Na2SO4, the crude mixture 3 or 4 were subjected to flash column chromatography (ethyl acetate: petroleum ether, 1:5) to give products, bmIm]OH was rinsed with ethyl acetate, dried under a vacuum, and recycled.
