Cobalt(<scp>I</scp>)‐Catalyzed Asymmetric [2+2+2] Cycloaddition of Alkynes and Nitriles: Synthesis of Enantiomerically Enriched Atropoisomers of 2‐Arylpyridines

A new flavor of chiral induction in the [2+2+2] cycloaddition yielding pyridines: Atropoisomers were prepared in the reaction of alkynes and nitriles in the presence of 1 mol % chiral CoI catalysts such as 1 with high yields and up to 93 % ee.
