Ethyl 2-[6-(4-methyl-benzo-yl)-7-phenyl-2,3-di-hydro-1H-pyrrolizin-5-yl]-2-oxo-acetate.

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 di-hydro-pyrrolizine 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 methyl-benzoyl rings are 41.65?(11) and 66.30?(8)°, respectively. In the crystal, weak C-H?O hydrogen bonds and C-H?? inter-actions occur. One mol-ecule is linked to five adjacent ones through eight hydrogen bonds, forming a three-dimensional network.

Crystal structure of ethyl N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-4-yl)carbamate.

Project description:In the title compound, C14H17N3O3, the dihedral angle between the benzene ring and the five-membered di-hydro-pyrazole ring is 52.26 (9)°. The ethyl ester group is approximately planar (r.m.s. deviation 0.0568 Å) and subtends an angle 67.73 (8)° to the pyrazole ring. In the crystal, molecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(10) ring motif. Weaker C-H⋯O contacts link these dimers into a three-dimensional network of mol-ecules stacked along the a-axis direction. Offset π-π stacking inter-actions between the benzene rings [centroid-to-centroid distance = 3.8832 (12) Å] further stabilize the crystal packing.

Crystal structure of (Z)-ethyl 2-{5-[(2-benzyl-idene-3-oxo-2,3-di-hydro-benzo[b][1,4]thia-zin-4-yl)meth-yl]-1H-1,2,3-triazol-1-yl}acetate.

Project description:The title compound, C22H20N4O3S, features two fused six-membered rings linked to a 1,2,3-triazole ring which is attached to an ethyl acetate group. The heterocycle in the benzo-thia-zine residue has an envelope conformation with the S atom being the flap. The conformation of the ethyl acetate side chain, which is directed to the same side of the mol-ecule as the C6 ring of the fused-ring system, may be partially established by a pair of weak intra-molecular C-H⋯O(carbon-yl) inter-actions. The three-dimensional packing is aided by inter-molecular C-H⋯O and C-H⋯N inter-actions.

Project description:In the title compound, C13H15N3O5S, the two rings face each other in a 'V' form at the S atom, with one N-H?O=S and one C-H?O=S contact from the pyrazolyl substituents to the sulfonyl group. Two classical hydrogen bonds from the amine group, one of the form N-H?O=S and one N-H?O=Coxo, link the mol-ecules to form layers parallel to the bc plane.

Project description:The title compound, C19H19N3O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the pyrazole ring adopts a slightly disordered half-chair conformation while in B it is planar [r.m.s. deviation = 0.0386?(15)?Å]. The dihedral angle between the mean planes of the two phenyl rings is 56.2?(8) in A and 38.2?(3)° in B. The N-phenyl substituent on the pyrazole ring is twisted by 46.5?(2) in A and 58.6?(4)° in B while the extended phenyl ring is twisted by 82.2?(8) in A and 87.5?(9)° in B. The mean plane of the amide group forms an angle of 74.8?(3) in A and 67.7?(1)° in B with respect to the phenyl ring. In addition, the amide group is rotated by 51.4?(1) in A and 53.6?(2)° in B from the the mean plane of the pyrazole ring. In the crystal, the two molecules are linked via N-H?O hydrogen bonds, supported by weak C-H?O inter-actions, forming dimers enclosing an R 2 (2)(10) ring motif. The dimers are linked via C-H?O inter-actions, forming a three-dimensional structure.

Synthesis and structure of ethyl 2-[(4-oxo-3-phenyl-3,4-di-hydro-quinazolin-2-yl)sulfan-yl]acetate.

Project description:The title compound, C18H16N2O3S, was synthesized by reaction of 2-mercapto-3-phenyl-quinazolin-4(3H)-one with ethyl chloro-acetate. The quinazoline ring forms a dihedral angle of 86.83?(5)° with the phenyl ring. The terminal methyl group is disordered by a rotation of about 60° in a 0.531?(13): 0.469?(13) ratio. In the crystal, C-H?O hydrogen-bonding inter-actions result in the formation of columns running in the [010] direction. Two parallel columns further inter-act by C-H?O hydrogen bonds. The most important contributions to the surface contacts are from H?H (48.4%), C?H/H?C (21.5%) and O?H/H?O (18.7%) inter-actions, as concluded from a Hirshfeld analysis.

Project description:The reaction of 1,5-dibenzyl-3-propargyl-1,5-benzodiazepine-2,4-dione with ethyl azido-acetate in the presence of copper sulfate pentahydrate and sodium ascorbate leads to the formation of the title regioisomer, C(30)H(29)N(5)O(4), which features a phenyl-ene ring fused with a seven-membered diazepinyl ring. The latter ring adopts a boat conformation (with the methyl-triazolylacetate-bearing C atom as the prow and the fused-ring C atoms as the stern). The benzyl groups connected to the diazepinyl ring jprotrude from the sides; the methyl-triazolylacetate substituent occupies an axial position.
