Crystal structure of 14-methyl-11-(3-methyl-phen-yl)-12-oxa-8,14-di-aza-tetra-cyclo-[8.3.3.0(1,10).0(2,7)]hexa-deca-2(7),3,5-triene-9,13-dione.

ABSTRACT: In the title compound, C21H20N2O3, the lactone ring adopts an envelope conformation with the quaternary C atom bonded to two other C atoms as the flap. The fused pyrrolidine ring adopts a twisted conformation about the Cq-N (q = quaternary) bond. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds generate R 2 (2)(8) loops. The dimers are linked into [110] chains by pairs of C-H?O inter-actions, which generate R 2 (2)(14) loops.

In the crystal, A+A and B+B inversion dimers linked by pairs of N-H⋯O hydrgen bonds occur; in both cases, R 2 (2)(8) loops are generated. A weak C-H⋯O inter-action is also observed, which links the dimers into [010] chains.

The β-lactam ring is planar [maximum deviation = 0.0044 (16) Å] and forms dihedral angles of 30.61 (9) and 85.51 (9)°, respectively, with the attached meth-oxy-phenyl and phen-oxy rings. The crystal packing is stabilized by N-H⋯O and C-H⋯O inter-actions forming R(2) (2)(8), R(2) (2)(20) and R(2) (2)(14) ring motifs. The crystal structure is further consolidated by weak C-H⋯π inter-actions.

Crystal structures and conformations of two Diels-Alder adduct derivatives: 1,8-bis-(thio-phen-2-yl)-14-oxa-tetra-cyclo-[6.5.1.0(2,7).0(9,13)]tetra-deca-2(7),3,5-trien-10-one and 1,8-diphenyl-14-oxa-tetra-cyclo[6.5.1.0(2,7).0(9,13)] tetra-deca-2,4,6-trien-10-one.

Project description:The title compounds, C21H16O2S2 (I) and C25H20O2 (II), are products of a tandem 'pincer' Diels-Alder reaction consisting of [2 + 2] cyclo-additions between benzo[c]furan and cyclo-penta-none. Each comprises a fused tetra-cyclic ring system containing two five-membered rings (in envelope conformations with the O atom as the flap) and six-membered rings (in boat conformations). In addition, two thio-phene rings in (I) and two phenyl rings in (II) are attached to the tetra-cyclic ring system. The cyclo-penta-none ring adopts a twisted conformation in (I) and an envelope conformation in (II). In (I), the thio-phene rings are positionally disordered over two sets of sites, with occupancy ratios of 0.901?(2):0.099?(2) and 0.666?(2):0.334?(2). In (II), the oxygen atom of the cyclo-penta-none ring is rotationally disordered over two sites with an occupancy ratio of 0.579?(4):0.421?(4). The mol-ecular structure of (I) is stabilized by an intra-molecular C-H?O hydrogen bond, which generates an S(7) ring motif. In the crystal, the mol-ecules are linked via weak C-H?O hydrogen bonds, which generate R (2) 2(16) ring motifs in (I) and C(8) chains in (II). In both structures, the crystal packing also features C-H?? inter-actions. The crystal studied of compound (I) was twinned by non-merohedry. The twin component is related by the twin law [-1 0 0 -0.101 1 -0.484 0 0 -1] operated by a twofold rotation axis parallel to the b axis. The structure of (I) was refined with a twin scale factor of 0.275?(2).
