Methyl 3-(4-bromo-phen-yl)-1-methyl-1,2,3,3a,4,9b-hexa-hydro-benzo[f]chromeno[4,3-b]pyrrole-3a-carboxyl-ate.

ABSTRACT: In the title compound, C(24)H(22)BrNO(3), the dihydro-pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in an envelope conformation. The bromo-phenyl group is oriented at an angle of 66.44?(4)° with respect to the naphthalene ring system. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by C-H?? inter-actions and the dimers are connected via C-H?Br hydrogen bonds. The crystal structure is further stabilized by ?-? inter-actions [centroid-centroid distance = 3.453?(1)?Å].

In the title compound, C(24)H(22)BrNO(3), the dihydro-pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in an envelope conformation. The bromo-phenyl group is oriented at an angle of 66.44 (4)° with respect to the naphthalene ring system. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by C-H⋯π inter-actions and the dimers are connected via C-H⋯Br hydrogen bonds. The crystal structure is further stabilized by π-π inter-actions [centroid-cent  ...[more]
