実験手順

To a 250 ml round bottom flask equipped with a stir bar was added 5 g (0.03 mol) tris(hydroxymethyl) nitromethane, 3.75 g (0.36 mol) 2,2-dimethoxypropane, 100 ml acetonitrile and 6 drops concentrated hydrochloric acid. The reaction was heated to 80° C. for 18 hours. After cooling to room temperature tte volatiles were removed in vacuo to give a white solid 2,2-dimethyl-5-hydroxy methyl-5-nitro-1,3-dioxane in 82% yield.
