Strategy to Construct Polycyclic Scaffolds via Formal Aza‐Diels‐Alder Reaction of Dihydro‐β‐Carboline with Heterodiene Precursor

Abstract The formal aza‐Diels‐Alder reaction of dihydro‐ β ‐carboline with heterodiene mediated by caesium carbonate has been described. This pathway provided a mild approach to functionalized polycyclic frameworks in 41%–91% yields.
