(RS/SR)-2-Oxo-4-phenyl-azetidin-3-yl acetate.

ABSTRACT: In the title compound, C(11)H(11)NO(3), a modified synthetic acetate derivative, the four memebered ?-lactam ring is roughly planar, with a maximum deviation of 0.21?(3)?Å, and makes a dihedral angle of 81.46?(14)° with the phenyl ring. In the crystal, a single N-H?O hydrogen bond links mol-ecules into a chain parallel to the a axis and thus stabilizes the structure. Although the absolute configuration could not be reliably determined, the compound corresponds to the diasteroisomer (RS/SR).

In the title compound, C(11)H(11)NO(3), a modified synthetic acetate derivative, the four memebered β-lactam ring is roughly planar, with a maximum deviation of 0.21 (3) Å, and makes a dihedral angle of 81.46 (14)° with the phenyl ring. In the crystal, a single N-H⋯O hydrogen bond links mol-ecules into a chain parallel to the a axis and thus stabilizes the structure. Although the absolute configuration could not be reliably determined, the compound corresponds to the diasteroisomer (RS/SR). ...[more]

4-{[(4Z)-5-Oxo-2-phenyl-4,5-dihydro-1,3-oxazol-4-yl-idene]meth-yl}phenyl acetate.

Project description:The title mol-ecule, C(18)H(13)NO(4), shows a dihedral angle between the terminal acetyl group (r.m.s. deviation = 0.0081?Å) and remaining non-H atoms (r.m.s. = 0.0734?Å) of 53.45?(7)°. The configuration about the central olefinic bond is Z and overall the mol-ecule has a U-shaped conformation. Supra-molecular chains along the b-axis direction are found in the crystal structure. These are stabilized by (C=O)??(ring centroid of the 1,3-oxazole ring) inter-actions [3.370?(2)?Å].

Project description:In the title mol-ecule, C(35)H(33)N(3)O(6), the pyrrolidine ring adopts a twist conformation. The mol-ecules are paired into centrosymmetric dimers by weak inter-molecular C-H?O hydrogen bonds. The dimers inter-act further again via C-H?O hydrogen bonds and N-H?O intramolecular interaction also stabilize the crystal packing.

Crystal structures of the two epimers from the unusual thermal C6-epimerization of 5-oxo-1,2,3,5,5a,6,7,9b-octa-hydro-7,9a-ep-oxy-pyrrolo-[2,1-a]iso-indole-6-carb-oxy-lic acid, 5a(RS),6(SR),7(RS),9a(SR),9b(SR) and 5a(RS),6(RS),7(RS),9a(SR),9b(SR).

Project description:The isomeric title compounds, C12H13NO4 (Ia) and C12H13NO4 (IIa), the products of an usual thermal C6-epimerization of 5-oxo-1,2,3,5,5a,6,7,9b-octa-hydro-7,9a-ep-oxy-pyrrolo-[2,1-a]iso-indole-6-carb-oxy-lic acid, represent the two different diastereomers and have very similar mol-ecular geometries. The mol-ecules of both compounds comprise a fused tetra-cyclic system containing four five-membered rings (pyrrolidine, pyrrolidinone, di-hydro-furan and tetra-hydro-furan), all of which adopt the usual envelope conformations. The dihedral angle between the basal planes of the pyrrolidine and pyrrolidinone rings are 14.3?(2) and 16.50?(11)°, respectively, for (Ia) and (IIa). The nitro-gen atom has a slightly pyramidalized geometry [bond-angle sum = 355.9 and 355.3°, for (Ia) and (IIa)], respectively. In the crystal of (Ia), mol-ecules form zigzag-like hydrogen-bonded chains along [010] through strong O-H?O hydrogen bonds and are further linked by weak C-H?O hydrogen bonds into complex two-tier layers parallel to (100). Unlike (Ia), the crystal of (IIa) contains centrosymmetric cyclic hydrogen-bonded dimers [graph set R22(14)], formed through strong O-H?O hydrogen bonds and are further linked by weak C-H?O hydrogen bonds into ribbons extending across [101].

Ethyl 2-[1-(3-methyl-but-yl)-4-phenyl-1H-1,2,3-triazol-5-yl]-2-oxo-acetate.

Project description:In the title compound, C17H21N3O3, the non-planar (r.m.s. deviation = 0.212?Å) ethyl (oxo)acetate group is oriented towards the phenyl substituent. The triazole and benzene rings are twisted with respect to each other, making a dihedral angle of 41.69?(6)°. In the crystal, mol-ecules are arranged into centrosymmetric R 2 (2)(10) dimers via pairs of C-H?O inter-actions involving the ethyl (oxo)acetate groups. In addition, the triazole rings show ?-? stacking inter-actions, with their centroids at a distance of 3.745?(2)?Å.

Racemic (RS(C),SR(S))-(2-{[1-allyl-oxy-carbonyl-3-(methyl-sulfanyl)prop-yl]iminometh-yl}phenyl-?S,N,C)chlorido-platinum(II).

Project description:The title compound, [Pt(C(15)H(18)NO(2)S)Cl], was obtained by the cyclo-metallation reaction of cis-bis-(benzonitrile)dichlorido-platinum(II) with N-benzyl-idene-l-methio-nine allyl ester in refluxing toluene. The Pt(II) atom has a square-planar geometry and is tetra-coordinated by the Cl atom and the C, N and S atoms from the benzyl-idene methio-nine ester ligand. In the crystal structure, the S atoms show opposite chiral configurations with respect to the ?-carbon of the methio-nine, reducing steric repulsion between the methyl and allyl ester groups.
