Polycyclic/multisubstituted pentafulvenes are of interest as they frequently occur in biologically relevant motifs, electrochromic dyes, and solar cells. Here, the authors report an enantioselective homologating annulation of cyclopent-4-ene-dione with 3-cyano-4-methylcoumarins through L-tert-leucine derived thiourea catalysis, affording a wide range of enantioenriched polycyclic multi-substituted embedded aminopentafulvenes.
