Dimethyl 2-[4-(hydroxymethyl)benzyl]-3-isopropylmaleate → 2-(4-Formylbenzyl)-3-isopropylmaleic acid dimethyl ester

Participants

Reaction Steps

To a solution of dimethyl 2-[4-(hydroxymethyl)benzyl]-3-isopropylmaleate (96 mg, 0.31 mmol) in benzene (2.0 mL) was added active manganese dioxide (602 mg), and the mixture was vigorously stirred at room temperature for 3 h. After the reaction mixture was filtered, the filtrate was concentrated to dryness to give 79 mg of 2-(4-formylbenzyl)-3-isopropylmaleic acid dimethyl ester as colorless oil (yield: 83%).
