Reaction Steps

p-Toluenesulfonylmethyl isocyanide (693 mg) and tert-butanol (438 μl) were added to a solution of 2,2-dimethyltetrahydro-4H-pyran-4-one (350 mg) in dimethoxyethane (10 ml) with stirring. Potassium tert-butoxide (766 mg) were added in three portions under cooling at −20° C. The mixture was heated to room temperature and then stirred for 18 hours. Diethyl ether was added and the mixture was filtered through Celite. Thereafter, the solvent was evaporated under reduced pressure to give the title compound (321 mg).
