Aza Diels-Alder Reactions of Nitriles, N, N-Dimethylhydrazones, and Oximino Ethers. Application in Formal [2 + 2 + 2] Cycloadditions for the Synthesis of Pyridines
Metal-free, formal [2 + 2 + 2] cycloaddition st rategies for the synthesis of polycyclic pyridine derivatives are described. The overall transformation proceeds via a two-stage pericyclic cascade mechanism. In the first step, an intramolecular propargylic ene reaction generates a vinyl-allene that i...
