Participants

Reaction Steps

n-Butyl lithium (a 1.6 M solution in THF; 19.0 ml, 30.4 mmol) was added to a solution of morpholine (2.67 ml, 30.4 mmol) in THF (20 ml) at -78 degrees C. under argon. After 20 minutes, 3-furaldehyde (1.8 ml, 28.9 mmol) was added, followed by s-butyl-lithium (a 1.3 M solution in cyclohexane; 23.4 ml, 30.4 mmol) after another 20 minutes. Stirring was continued for 2 hours and chlorotriethylsilane (5.1 ml, 30.4 mmol) was added. After 2 hours at -78 degrees C., s Buli (23.4 ml, 30.4 mmol) was added, followed by iodomethane (5.4 ml, 86.9 mmol) after another 2 hours. The mixture was stirred at room temperature for 15 hours and quenched with ice cold dilute hydrochloric acid. Extraction with ethyl ether and evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by flash chromatography on silica using 10% diethyl ether/hexane to give the titled aldehyde.
