Cobalt-Catalyzed [2+2+2] Cycloadditions of Alkynyl Yndiamides with Nitriles
{{output}}
Herein is described a convenient cobalt-catalyzed [2+2+2] cycloaddition of alkynyl yndiamides with nitriles. This regioselective reaction provides access to 39 novel valuable 2,3-dihydro-1H-pyrrolo[2,3-c]pyridin-7-amine or (1,2,3,4-tetrahydro-1,7-naphthyridin-... ...
