【 摘 要 】

The title compound, C20H27ClN2O3, was obtained via an original synthesis method. The central heterocyclic ring adopts a shallow envelope conformation, with the N atom bearing the cyclo­pentane ring as the flap [deviation from the other atoms = 0.442 (2) Å]. The cyclo­pentane ring adopts a twisted conformation about one of the CN—C bonds: the exocyclic C—N bond adopts an equatorial orientation. The dihedral angles between the central ring (all atoms) and the pendant five- and six-membered rings are 10.3 (2) and 87.76 (14)°, respectively. In the crystal, C—H⋯O inter­actions link the mol­ecules into [011] chains. A weak C—H⋯Cl inter­action links the chains into (100) sheets. A mechanism for the cyclization reaction is proposed.
