ABSTRACT: In the title compound, C(22)H(17)N(3)O(5), synthesized via the aza-Wittig reaction of ethyl 3-(phenyl-imino-methyl-ene-amino)-benzofuran-2-carboxyl-ate, benzene isocyanate and diethyl 2-amino-succinate, the imidazo[1,2-a]benzo[4,5]furo[2,3-d]pyrim-idine ring system is essentially planar (r.m.s. deviation for all 16 non-H atoms = 0.020?Å). The phenyl ring is twisted with respect to this ring system, making a dihedral angle of 54.23?(4)°. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions.

Project description:In the title compound, C(21)H(22)N(2)O(4), the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å).

3-(4-Chloro-phen-yl)-2-(diisopropyl-amino)-1-benzofuro[3,2-d]pyrimidin-4(3H)-one.

Project description:In the mol-ecule of the title compound, C(22)H(22)ClN(3)O(2), the three fused rings of the benzofuro[3,2-d]pyrimidine system are almost coplanar. This ring system is oriented with respect to the substituted benzene ring at a dihedral angle of 79.05 (3)°. Intra-molecular C-H⋯N hydrogen bonding results in the formation of a six-membered ring. In the crystal structure, π-π stacking inter-actions involving the furan, pyrimidinone and benzene rings are present [centroid-to-centroid distances in the range 3.258 (1)-3.870 (1) Å].

Project description:In the title compound, C(7)H(7)N(2)O(+)·I(-), the carbonyl C and O atoms of the cation and the iodide ion are situated on mirror planes.

2-(2-Hydroxy-ethyl-amino)-3-phenyl-1-benzofuro[3,2-d]pyrimidin-4(3H)-one dichloro-methane hemisolvate.

Project description:In the title compound, C(18)H(15)N(3)O(3)·0.5CH(2)Cl(2), the fused ring benzofuro[2,3-d]pyrimidine system is essentially planar [maximum deviation 0.029?(1)?Å]. The planes of the pyrimidinone and phenyl rings are nearly perpendicular [dihedral angle = 87.50?(14)°]. The packing of the mol-ecules in the crystal structure is governed mainly by inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions and inter-molecular ?-? inter-actions between benzofuro[3,2-d]pyrimidine units [the interplanar distances are ca 3.4 and 3.5?Å, and the distances between adjacent ring centroids are in the range 3.64?(1)-3.76?(1)?Å]. The dichloromethane solvent molecule lies on a special position.

6-(2-Chloro-benz-yl)-1-(4-chloro-phen-yl)-7-hy-droxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one.

Project description:The title compound, C(19)H(15)Cl(2)N(3)O(2), was obtained by a one-step cyclo-condensation of 2-amino-1-(4-chloro-phen-yl)imidazoline with diethyl (2-chloro-benz-yl)malonate under basic conditions. In the crystalline state, the mol-ecule exists as the 7-hy-droxy-5-oxo tautomer. The dihedral angles between the fused imidazopyrimidine and aromatic chloro-phenyl and chloro-benzyl rings are 14.2?(1) and 70.7?(1)°, respectively. The conformation of the mol-ecule is influenced by the intra-molecular C-H?O and C-H?N hydrogen bonds, giving a nearly planar five-ring fused system [maximum deviation from the mean plane = 0.296?(2)?Å]. In the crystal structure, strong inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains along the c axis. These chains are further stabilized by weak C-H?Cl and ?-? inter-actions [centroid-centroid distance = 3.6707?(12)?Å].

Project description:The asymmetric unit of the title compound, C(22)H(16)ClN(3)O(5), consists of two crystallographically independent mol-ecules. The fused rings of the imidazo[1,2-a]benzo[4,5]furo[3,2-d]pyrimidine system are nearly coplanar and the chlorophenyl rings are twisted with respect to the two pyrimidinone ring systems by 71.00?(2) and 62.59?(2)°. The C atoms of the ethyl side chain are disordered and were refined using a split model. In the crystal structure, the mol-ecules are connected via weak intra- and inter-molecular C-H?O inter-actions are present. The ethyl group in one molecule is disordered over two positions, with site occupancy factors 0.55 and 0.45; in the other molecule only the methyl group is disordered over two positions, with site occupancy factors 0.6 and 0.4.

2-[4-(Piperidin-1-yl)-5H-chromeno[2,3-d]pyrimidin-2-yl]phenol.

Project description:In the title compound, C22H21N3O2, the pyrimidine ring is essentially planar [maximum deviation = 0.018?(2)?Å] and forms dihedral angles of 22.70?(8) and 0.97?(7)°, respectively, with the fused benzene ring and the hy-droxy-substituted benzene ring. The piperidine ring has a chair conformation and the pyran ring has a flattened twist-boat conformation. The hy-droxy group was refined as disordered over two sets of sites in a 0.702?(4):0.298?(4) ratio. The disorder corresponds to a rotation of approxomiately 180° about the C-C bond connecting the phenol group to the pyrimidine ring and hence, both the major and minor components of disorder form intra-molecular O-H?N hydrogen bonds. In the crystal, pairs of weak C-H?? inter-actions form inversion dimers. In addition, ?-? inter-actions are observed between the pyrimidine ring and the hy-droxy-substituted benzene ring [centroid-centroid separation = 3.739?(2)?Å].

Ethyl 2-(2-acetoxy-benzyl-idene)-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-1,3-thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.

Project description:In the title mol-ecule, C(25)H(22)N(2)O(5)S, the atoms of the thia-zolopyrimidine ring system, with the exception of the phenyl-bearing C atom [deviation = 0.177?(2)?Å], are essentially planar [r.m.s deviation = 0.100?(2) °] and the mean plane of these atoms forms dihedral angles of 89.86?(10) and 7.97?(8)° with the phenyl and benzene rings, respectively. In the crystal, co-operative C-H?O and C-H?? inter-actions lead to a supra-molecular chain along the a axis. These chains are connected via ?-? inter-actions [centroid-centroid = 3.7523?(13)?Å].
