Reaction Steps

A solution of 1.0 grams (3.82 mmol) of the above aldehyde, 0.85 mL of ethylene glycol, 20 mg of p-toluenesulfonic acid and 42 mL of toluene was refluxed under nitrogen for 18 hours, cooled and concentrated in vacuo. The residue was redissolved in 50 mL of CH2Cl2, washed with saturated aqueous NaHCO3, dried over MgSO4 and concentrated to an oil. Chromatography on silica gel (10% ethyl acetate (EtOAc): 90% hexane) gave 2-(5-iodo-2-methoxyphenyl)-1,3-dioxolane as a clear oil, 0.68 grams (58%).
