- Abstract
- Furans containing a β-ketoester group at 2-position undergo oxidative ring-opening by Mn(III)/Co(II) catalysts under an O2 atmosphere to produce 1,4-dicarbonyl moieties through an endoperoxide intermediate, which consecutively cyclized with the β-ketoester unit to afford 4-hydroxy-2-cyclohexen-1-ones. This oxidation/cyclization products were efficiently transformed into versatile benzofuran derivatives after consecutive aromatization and Paal–Knorr reaction.
