2'-Methyl-3,5-diphenyl-spiro-[4,6-dioxa-2-aza-bicyclo-[3.2.0]hept-2-ene-7,4'-iso-quinoline]-1',3'(2'H,4'H)-dione.

ABSTRACT: In the title compound, C(25)H(18)N(2)O(4), the tetra-hydro-pyridine ring adopts a distorted envelope conformation with the spiro C atom at the flap position [deviation = 0.470?(2)?Å]. The dihydro-oxazole ring is planar (r.m.s. deviation = 0.013?Å) and it makes dihedral angles of 73.43?(8) and 4.24?(8)° with the two attached phenyl rings. The dihedral angle between oxetane and oxazole planes is 67.44?(9)°. In the crystal structure, C-H?O hydrogen bonds link neighbouring mol-ecules into zigzag chains along the b axis and these chains are linked via C-H?? inter-actions.

1'-Acetyl-3-phenyl-6-oxa-4-thia-2-aza-spiro-[bicyclo-[3.2.0]hept-2-ene-7,3'-indolin]-2'-one.

Project description:In the title indoline compound, C(19)H(14)N(2)O(3)S, the pyrrolidine ring adopts an envelope conformation with the four-connected (spiro) C atom as the flap [displacement = 0.148 (3) Å]. The mean plane formed through the indoline unit is inclined at dihedral angles of 89.92 (16) and 59.54 (12)° with the thia-zole and phenyl rings, respectively; the dihedral angle between the latter rings is 9.55 (14)°. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into inversion dimers, producing R(2) (2)(6) hydrogen-bond ring motifs. Weak inter-molecular C-H⋯π as well as π-π inter-actions [centroid-centroid distance = 3.4041 (15) Å] further consolidate the crystal structure.

3-(2,6-Dioxopiperidin-3-yl)-3-aza-bicyclo-[3.2.0]heptane-2,4-dione.

Project description:The title mol-ecule, C(11)H(12)N(2)O(4), consists of a 3-aza-bicyclo-[3.2.0]heptane group containing a nearly planar cyclo-butane ring (r.m.s. deviation of fitted atoms is 0.0609?Å), fused to a pyrrolidine ring, bonded to a 2,6-dioxopiperidine ring at the 3-position. The angle between the mean planes of the cyclo-butane and fused pyrrolidine ring is 67.6?(6)°. The dihedral angles between the mean planes of the pyrrolidine and cyclo-butane rings and the dioxopiperidine ring are 73.9?(2) and 62.4?(4)°, respectively. The pyrrolidine and dioxopiperidine rings are twisted about the 3-yl group [torsion angles = -55.0?(1) and 115.0?(1)°] in a nearly perpendicular manner. Crystal packing is influenced by extensive inter-molecular C-H?O and N-H?O inter-actions between all four carbonyl O atoms and H atoms from the cyclo-butane and dioxopiperidine rings, as well as between the N atom and an H atom from the cyclo-butane ring. In addition, weak ?-ring interactions also occur between H atoms from the cyclobutane ring and the five-membered pyrrolidine ring. As a result, mol-ecules are linked into infinite chains diagonally along the [101] plane of the unit cell in an alternate inverted pattern.
