An unprecedented cycloaddition of vinyl diazo compounds with benzofuran-derived azadienes catalyzed by rarely independently used NaBArF4has been established. Benzofuran-fused hydropyridines were constructed with excellent yields and high diastereoselectivity via a Na+-catalyzed inverse-electron-demand aza-Diels–Alder reaction. Notably, this transformation also features good compatibility with a one-pot protocol to deliver the spiro[benzofuran-cyclopentene] skeleton, as well as perfect atom economy and simple reaction conditions. |
