A chiral cyclopentadienyl cobalt(III)-catalyzed enantioselective [4 + 1] annulation of N-chlorobenzamides with cyclopropenes is reported. The cobalt catalyst engages in the C-H activation as well promotes C-C bond cleavage cyclopropene, rendering it a one-carbon unit for annulation. reaction efficiently constructs biologically relevant isoindolinones selectivities up to 99:1 er and >20:1 E/Z ratios. cobalt(III) displays unique orthogonal reactivity profile delivering products, whereas its rhodium(III) homologue more classical 2] pattern. Computational studies reveal origin these divergences.
