Direct CuO nanoparticle-catalyzed synthesis of poly-substituted furans via oxidative C–H/C–H functionalization in aqueous medium†
Abstract
Here, we have reported synthesis of 3,4-dicarbonyl substituted poly-functionalized furan derivatives via direct functionalization of α,β-unsaturated carbonyl compounds through conjugate addition initiated domino reactions using CuO nanoparticles as a reusable catalyst in aqueous ethanol.
