title: 8-Phenyl-3,4,6,7,8,8a-hexahydro-1H-pyrrolo-[2,1-c][1,4]oxazin-6-one.
abstract: In the title compound, C(13)H(15)NO(2), the hexa-hydro-pyrrolo-[2,1-c][1,4]oxazine fragment is disordered over two conformations (A and B) in a 0.656 (5):0.344 (5) ratio. The five-membered ring is similarly disordered and adopts an envelope conformation in A, while in B this ring is nearly planar [maximum deviation = 0.088 (1) Å]. The six-membered rings in both A and B exhibit chair conformations. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagating in [010].
