trans-4-Hydroxycyclohexane-1-carboxylic acid benzyl ester → Benzyl 4-oxocyclohexane-1-carboxylate

Participants

Reaction Steps

To a solution of benzyl 4-hydroxycyclohexane carboxylate (32.1 g, 137.2 mmol) in 400 mL of dichloromethane was added pyridinium chlorochromate (68.8 g, 274.0 mmol) in portions over 10 minutes. After two hours, the reaction was filtered through a large plug of silica gel eluting with 30% ethyl acetate in hexane to afford benzyl 4-oxocyclohexane carboxylate as an oil.
