1-[2-Oxo-1′-phenyl-2′,3′,5′,6′,7′,7a'-hexahydroindoline-3-spiro-3′-1′H-pyrrolizin-2′-yl]-3-phenylprop-2-en-1-one

Abstract

In the title compound, C29H26N2O2, one of the pyrrolidine rings in the pyrrolizine system is disordered, with site occupancies of ca 0.55 and 0.45. Both components of the disordered pyrrolidine ring adopt envelope conformations, whereas the other pyrrolidine ring adopts a twist conformation. The molecules are linked into centrosymmetric dimers by N—H...O hydrogen bonds and the dimers are connected via C—H...π interactions.
