Trimethyl orthoformate → (2-Methoxy-1,3-dioxan-5-yl)methanol

참여 물질

반응 단계

A mixture of 2-(hydroxymethyl)-1,3-propanediol (1.7 g, 16 mmol), trimethyl orthoformate (7 ml, 64.1 mmol), and p-toluenesulfonic acid monohydrate (275 mg, 1.6 mmol) was stirred at room temperature for 22 hours. To the reaction mixture, triethylamine (447 μl) was added and the mixture was concentrated. The residue was purified by silica gel column chromatography (elution solvent: heptane/ethyl acetate) to obtain the title compound (1.4 g, 59.1% yield), which is a cis and trans (1:1) mixture, as a light yellow oil.
