4'-Methyl-14',19'-dioxa-4'-aza-spiro-[acenaphthyl-ene-1,5'-tetra-cyclo-[18.4.0.0(2,6).0(8,13)]tetra-cosa-ne]-1'(24'),8',10',12',20',22'-hexa-ene-2,7'(1H)-dione.

ABSTRACT: In the title compound, C33H29NO4, the acenaphthyl-ene ring system is essentially planar (r.m.s. deviation = 0.0290 Å). The pyrrolidine ring adopts a C-envelope conformation with a C atom displaced by 0.671 (2) Å from the mean-plane formed by the remaining ring atoms. The pyrrolidine ring is fused to acenaphthyl-ene ring system making a dihedral angle of 88.0 (7)°. In the crystal, mol-ecules are linked into R(2)2(9) dimers via C-H⋯N and C-H⋯O hydrogen bonds. Two C atoms act as donors to the same O atom acceptor, resulting in the formation of R(2)1(7) ring motifs. These two motifs combine to form hydrogen-bonded sheets running along the a- and b-axis directions.
