Reaction Conditions

Reaction Steps

Ex-6a) A suspension of potassium t-butoxide (200 g, 1.78 mol) in toluene which was cooled to 0° C. in an ice bath under N2 was treated with cyclohexanone (157 g, 1.60 mol). To the reaction mixture was slowly added allyl bromide (194 g, 1.60 mol) over a 2 hour period. The reaction was warmed to room temperature over 5 hours. The reaction was then poured into EtOAc (400 mL) and washed once with 10% potassium hydrogen sulfate (250 mL). The organic solution was then washed with brine (3×200 mL), dried over magnesium sulfate, and evaporated under reduced pressure. The resulting oil was then chromatographed to yield 158.4 g (71.6%) of 2-allyl cyclohexanone as an oil.
