Ethyl 2-[6-(4-methylbenzoyl)-7-phenyl-2,3-dihydro-1H-pyrrolizin-5-yl]-2-oxoacetate

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 dihydropyrrolizine 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 methylbenzoyl rings are 41.65 (11) and 66.30 (8)°, respectively. In the crystal, weak C—H...O hydrogen bonds and C—H...π interactions occur. One molecule is linked to five adjacent ones through eight hydrogen bonds, forming a three-dimensional network.
