[2+2+2]=4 (stereocenters)? Nickel‐catalyzed multicomponent cycloadditions and alkenylative cyclizations involving two alkenes and one allene are described. The [2+2+2] cycloaddition provides rapid access to stereochemically complex, cis ‐fused hydrindanes. By exchanging P( o ‐tol) 3 for PBu 3 as ligand, the reaction pathway can be diverted to an alkenylative cyclization process.
