Azadiene Diels-Alder cycloaddition of fulvenes: a facile approach to the [1]pyrindine system.
[reaction: see text] Regioselective and stereoselective inverse-electron-demand Diels-Alder reaction of N-sulfonyl-1-aza-1,3-butadiene with fulvenes are described. The methodology provides an efficient and novel route to tetrahydro-[1]pyrindine systems.
