Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.056; wR factor = 0.167; data-to-parameter ratio = 16.0.In the title compound, C 32 H 28 F 2 N 2 O 2 , the tetrahydropyridine ring adopts a distorted boat conformation. The two fluorophenyl groups are attached to the tetrahydropyridine ring in a trans orientation. The dihedral angle between the planes of the fluoro-substituted rings is 57.0 (1). The amino group and carbonyl O atom are involved in intramolecular hydrogen bonding. In the crystal, weak C-HÁ Á ÁO, C-HÁ Á ÁF and C-HÁ Á Á interactions link the molecules into columns along [010].

A direct method for the synthesis of tetracyclic oxazepine-fused pyrroles has been developed through [3+2] annulation between aqueous succinaldehyde and dibenzo[b,f][1,4]oxazepines under metal-free conditions.
