Heterocyclic　ketene　N,N-acetals　are　versatile　building　blocks　for　the　synthesis　of　nitrogen-containing　heterocyclic　compounds.　In　the　present　work,　the　anodic　oxidation　of　catechols　2a-f　in　the　presence　of　alpha-oxoheterocychc　ketene　N,N-acetals　1a-d　has　been　investigated　using　cyclic　voltammetry　and　controlled-potential　electrolysis　methods.　These　results　indicate　that　alpha-oxoheterocyclic　ketene　N,N-acetals　could　undergo　Michael　addition　to　the　anodically　generated　o-benzo-quinones　and　produce　alpha-carbon-arylated　products　in　good　yields.　This　approach　provides　effective　and　＂green＂　access　to　the　synthesis　of　alpha-aryl　alpha-oxoheterocyclic　ketene　N,N-acetals　containing　an　electron-rich　aromatic　ring.　In　addition,　density　functional　theory　calculations　were　performed　to　explain　the　exclusive　formation　of　alpha-carbon-arylated　products.　((C)　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　69451　Weinheim,　Germany,　2009)
