چکیده
The asymmetric unit of the title compound, C(13)H(15)NO(2), the main product of a photoreaction, contains two crystallographically independent mol-ecules. In both mol-ecules, the conformation of the seven-membered ring is twist sofa and that of the five-membered rings is envelope. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.

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 conformatio...
