(3aR,8bR)-3a,8b-Dihy-droxy-2-methyl-sulfanyl-3-nitro-1-phenyl-1,8b-di-hydro-indeno[1,2-b]pyrrol-4(3aH)-one.

ABSTRACT: In the title compound, C18H14N2O5, the pyrrolidine ring adopts a shallow envelope conformation, with the C atom bearing the OH group (and remote from the N atom) displaced by 0.257?(2)?Å from the other atoms. The cyclo-pentane ring has a twisted conformation about the C-C bond bearing one =O and one -OH grouping. The dihedral angle between the five-membered rings (all atoms) is 65.54?(9)° and the OH groups lie to the same side of the ring-junction. The mol-ecular structure features a weak intra-molecular O-H?O bond and a possible C-H?? inter-action. In the crystal, the mol-ecules are linked into [010] chains by O-H?O hydrogen bonds. Weak C-H?O bonds connect the chains into (100) sheets.

Project description:The asymmetric unit of the title compound, C19H16N2O5S, contains four independent mol-ecules (A, B, C and D), with two mol-ecules (B and D) displaying disorder in their methyl-sulfanyl groups [occupancy ratios of 0.797 (11):0.203 (11) and 0.85 (2):0.15 (2)]. The nitro groups are twisted slightly out of the planes of the 2-pyrroline rings to which they are bonded with dihedral angles of 10.17 (1), 8.01 (1), 9.44 (1) and 8.87 (1)° in mol-ecules A, B, C and D, respectively. The 2-pyrroline rings are almost orthogonal to the attached tolyl rings, forming dihedral angles of 73.44 (1), 81.21 (1), 88.18 (8) and 73.94 (1)° for mol-ecules A, B, C and D, respectively. A weak intra-molecular O-H⋯O inter-action is observed in mol-ecules B and C. The two hy-droxy groups in each mol-ecule are involved in inter-molecular O-H⋯O hydrogen bonding. In the crystal, mol-ecules are connected via O-H⋯O and C-H⋯O hydrogen bonds, forming a complex three-dimensional network.

Project description:In the title compound, C19H16N2O6S, the pyrrolidine ring adopts a twisted conformation with puckering parameters q 2 = 0.088?(3)?Å and ?2 = 61.5?(14)°. The cyclo-pentane ring adopts a twisted conformation with puckering parameters q 2 = 0.099?(2)?Å and ?2 = 242.8?(14)°. A weak intra-molecular O-H?O inter-action occurs. In the crystal, pairs of C-H?O inter-actions generate dimers with graph-set motif R 2 (2)(24) and they are interconnected by pairs of O-H?O hydrogen bonds, which link the mol-ecules into inversion dimers with graph-set motif R 2 (2)(10).

Redetermination of ethyl (3a-cis)-3a,8b-dihydr-oxy-2-methyl-4-oxo-3a,8b-dihydro-4H-indeno[1,2-b]furan-3-carboxyl-ate monohydrate.

Project description:The crystal structure of the title compound, C(15)H(14)O(6)·H(2)O, has been redetermined from single-crystal X-ray data. The structure was originally determined by Peet et al. [J. Heterocycl. Chem. (1995), 32, 33-41] but the atomic coordinates were not reported or deposited in the Cambridge Structural Database. The ethyl substituent is disordered over two sites with refined occupancies of 0.815?(6) and 0.185?(6). The indeno group is almost planar [maximum deviation 0.0922?(14)?Å] and makes an angle of 68.81?(4)° with the furan ring. The fused ring molecules are assembled in pairs by intermolecular O-H?O hydrogen bonds. The resulting dimers are also hydrogen bonded to the water molecules, forming double-stranded chains running along the a axis.

Crystal structure of (±)-(3aR,5R,8bR)-5-hydroper-oxy-2-phenyl-6-tosyl-4,5,6,8b-tetra-hydro-pyrrolo-[3,4-e]indole-1,3(2H,3aH)-dione.

Project description:The title compound, C23H20N2O6S, crystallizes as a racemate in the space group P-1, with an overall L- or J-shape to each mol-ecule. Centrosymmetric pairs of mol-ecules are tandem hydrogen bonded between the hydro-per-oxy H atom and carbonyl O atom. A different centrosymmetric pairing has stacked S-tolyl rings, and a third pairing is L,J-inter-locked by the short leg. Except for stacked tolyl pairs, neighboring ?-systems are much closer to orthogonal than coaxial. The title compound is the first example of a hydro-peroxide obtained from the autoxidation of a Diels-Alder adduct of a 2-vinyl-pyrrole.

Ethyl 1'-methyl-2-oxo-4'-[(3aR,5R,5aS,8aS,8bR)-2,2,7,7-tetra-methyl-tetra-hydro-3aH-bis-[1,3]dioxolo[4,5-b:4',5'-d]pyran-5-yl]-2H-spiro-[ace-naphthyl-ene-1,2'-pyrrolidine]-3'-carboxyl-ate.

Project description:In the title mol-ecule, C30H35NO8, the ace-naphthyl-enone moiety, two atoms of a methyl pyrrolidine ring (N and C atoms) and four atoms of an ethyl acetate moiety (two C and two O atoms) are disordered over two sets of sites in ratio 0.532?(7):0.468?(7). The three C atoms of a di-meth-oxy-ethane ring and dioxolane ring attached with two methyl groups are disordered over two sets of sites in 0.66?(2):0.34?(2) and 0.62?(2):0.38?(2) ratios, respectively. The major and minor components of the ace-naphthyl-ene ring are essentially planar (r.m.s. deviations = 0.0254 and 0.0436?Å, respectively). The major and minor components of the pyrrolidine ring adopt C-envelope conformations with C atoms displaced by 0.492?(11) and 0.595?(7)?Å from the remaining ring atoms. One of the dioxolane rings is disordered with its major component in an envelope conformation [C displaced by 0.511?(11)?Å] and the minor fraction is more or less planar with an r.m.s. deviation of 0.070?Å. The other dioxolane ring is in an envelope conformation, with a C atom displaced by 0.438?(3)?Å from the remainder of the ring atoms. The crystal packing features C-H?O inter-actions, which generate C(9) chains.

Crystal structure of 4-methyl-N-{(E)-meth-yl[(3aR,8aS)-2-oxo-3,3a,8,8a-tetra-hydro-2H-indeno-[1,2-d][1,3]oxazol-3-yl]-λ(4)-sulfanyl-idene}benzene-sulfonamide.

Project description:The formulation that the title compound, C18H18N2O4S2, adopts is a zwitterionic core with the charge separated to the sulfilimine S and N atoms and is supported by the two different S-N bond distances about the sulfinimine N atom [1.594 (2) and 1.631 (2) Å, respectively] that are typical for such bonds. The notably unusual bond is S-N(oxazolidinone) [1.692 (2) Å] that is longer than a typical S-N bond [1.603 (18) Å, Mogul analysis; Macrae et al. (2008 ▸). J. Appl. Cryst. 41, 466-470]. The bond-angle sum about sulfilimine sulfur (308.35°) reflects the trigonal-pyramidal geometry of this atom. Two of the angles are less than 100°. Despite the pyramidalization of this sulfur, there are no significant inter-molecular inter-actions, beyond usual van der Waals contacts, in the crystal packing.

Project description:In the title compound, C(32)H(37)NO(8), the central pyran ring adopts a twist-boat conformation and the 1,3-dioxoane rings adopt envelope conformations. The acenaphthyl-enone unit and two C atoms of a pyrrolidine ring are disordered over two sets of sites [occupancy ratio 0.669?(7):0.331?(7)]. The major fraction of the disordered pyrrolidine ring exhibits an envelope conformation while the minor component is essentially planar [maximum deviation = 0.037?(12)?Å]. The other pyrrolidine ring also adopts an envelope conformation. The dihedral angle between the mean planes of the two wings of the pyrrolidine ring is 30.6?(2)°. Both the major and minor components of the acenaphthyl-enone unit are essentially planar, the maximum deviations being 0.025?(10) and 0.047?(19)?Å, respectively; the dihedral angle between the mean planes of the two components is 1.72?(3)°. The crystal packing features C-H?O inter-actions.

The two five-membered rings generated by the ep-oxy bridge of the six-membered ring adopt envelope conformations, whereas the N-containing five-membered ring adopts a twisted conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds.
