Spiro-[cyclo-pentane-1,2'(1'H)-pyrido[2,3-d]pyrimidin]-4'(3'H)-one.

ABSTRACT: The title compound, C(11)H(13)N(2)O, was obtained by cyclo-condensation of 2-amino-pyridine-3-carbonitrile with cyclo-penta-none. The mol-ecule is built up from two fused six-membered rings and one five-membered ring linked through a spiro C atom. Both the pyrimidine and the cyclo-pentane rings adopt envelope conformations. In the crystal structure, mol-ecules are linked by inter-molecular N-H?O hydrogen bonds.

Hexafluoroisopropyl alcohol mediated synthesis of 2,3-dihydro-4H-pyrido[1,2-a]pyrimidin-4-ones.

Project description:An efficient synthesis of novel 2,3-dihydro-4H-pyrido[1,2-a]pyrimidin-4-ones has been reported. Inexpensive and readily available substrates, environmentally benign reaction condition, and product formation up to quantitative yield are the key features of this methodology. Products are formed by the aza-Michael addition followed by intramolecular acyl substitution in a domino process. The polar nature and strong hydrogen bond donor capability of 1,1,1,3,3,3-hexafluoropropan-2-ol is pivotal in this cascade protocol.

3-(2-Chloro-ethyl)-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one.

Project description:In the title mol-ecule, C(11)H(11)ClN(2)O, the pyrido[1,2-a]pyrimidine ring system is planar (maximum deviation = 0.0148?Å) and the methyl C and carbonyl O atoms are nearly coplanar to it. The chloro-ethyl side chain is in a synclinal conformation, nearly orthogonal to the pyrimidine ring, with a dihedral angle between the chloro-ethyl side chain and the pyrimidine ring of 88.5?(1)°. Weak inter-molecular C-H?N and C-H?Cl hydrogen bonds along with ?-? inter-actions between the pyrimidine and pyridine rings [centroid-centroid distance is 3.538?(2)?Å] form a three-dimensional network. The crystal is a racemic twin with a 0.68?(12):0.32?(12) domain ratio. MOPAC AM1 and density functional theory (DFT) theoretical calculations at the B3-LYP/6-311+G(d,p) level support these observations.

Aqua-bis(2,3-dimethyl-4-oxo-4H-pyrido[1,2-a]pyrimidin-9-olato)nickel(II).

Project description:In the crystal structure of the mononuclear title complex, [Ni(C(10)H(9)N(2)O(2))(2)(H(2)O)], the Ni(II) ion is five-coordinated in a distorted square-pyramidal geometry by two N atoms and two O atoms from 2,3-dimethyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligands and one O atom from a water mol-ecule. O-H?O hydrogen bonds between the coordinated water mol-ecule and the ligand connect adjacent mol-ecules, forming a ribbon parallel to the b axis.

Crystal structure of (E)-9-(4-nitro-benzyl-idene)-8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one.

Project description:The title compound, C17H12N4O3, a pyrido-pyrrolo-pyrimidine derivative, is almost planar. The nitro-benzene ring is inclined to the mean plane of the 8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023 Å) by 6.8 (1)°. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds, forming layers parallel to (101).

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(26)H(26)N(4)OS. In each mol-ecule, the thienopyrimidine fused-ring system is essentially planar with a maximum deviation of 0.0409?(18) for the N atom. In one mol-ecule, this ring system forms diherdral angles of 84.8?(1) and 67.6?(1)° with the adjacent phenyl and benzyl rings, respectively, while the corresponding angles in the other mol-ecule are 77.9?(1) and 66.5?(1)°.

2,3-Tri-methyl-ene-7,8-di-hydro-pyrrolo-[1,2-a]thieno[2,3-d]pyrimidin-4(6H)-one.

Project description:The title mol-ecule, C12H12N2OS, is planar, with an r.m.s. deviation of 0.04 Å. In the crystal, the N atom adjacent to the carbonyl group is sp (2)-hybridized. The crystal structure is stabilized by π-π stacking inter-actions observed between thio-phene and pyrimidinone rings of c-glide-related mol-ecules [centroid-centroid distance = 3.9554 (13) Å] and by C-H⋯π inter-actions, forming an infinite chain along the c-axis direction.

6-(2,6-Dimethyl-phen-yl)pyrido[2,3-d]pyrimidin-7-amine.

Project description:In the title compound, C(15)H(14)N(4), the pyrido[2,3-d]pyrimidine system is almost ideally planar (r.m.s. deviation 0.028?Å) with its mean plane almost orthogonal to the 2,6-dimethyl-phenyl plane. The dihedral angle formed by these planes [87.3?(2)°] is close to the predicted value (89.7°) obtained by mol-ecular-mechanics force-field calculations. Only one of the two active amine H atoms participates in hydrogen bonding, which links mol-ecules into centrosymmetric dimers.

Project description:The title compound, C(20)H(20)O(3), was prepared by an acyl-oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material.
