Ethyl 2-[6-(4-methyl-benzo-yl)-7-phenyl-2,3-di-hydro-1H-pyrrolizin-5-yl]-2-oxo-acetate.

ABSTRACT: In the title compound, C25H23NO4, the pyrrolizine ring is approximately planar with an r.m.s deviation from planarity of 0.0053?Å, while the fused di-hydro-pyrrolizine ring adopts an envelope conformation with the C atom connected to two CH2 as the flap. The dihedral angles between the fused ring system and the phenyl and methyl-benzoyl rings are 41.65?(11) and 66.30?(8)°, respectively. In the crystal, weak C-H?O hydrogen bonds and C-H?? inter-actions occur. One mol-ecule is linked to five adjacent ones through eight hydrogen bonds, forming a three-dimensional network.

In the title compound, C25H23NO4, the pyrrolizine ring is approximately planar with an r.m.s deviation from planarity of 0.0053 Å, while the fused di-hydro-pyrrolizine ring adopts an envelope conformation with the C atom connected to two CH2 as the flap. The dihedral angles between the fused ring system and the phenyl and methyl-benzoyl rings are 41.65 (11) and 66.30 (8)°, respectively. In the crystal, weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions occur. One mol-ecule is linked to five adjac  ...[more]
