3-Isopropyl-2-(4-methoxy-phen-oxy)-1-benzo-furo[3,2-d]pyrimidin-4(3H)-one.

ABSTRACT: In the title compound, C(20)H(18)N(2)O(4), all non-H atoms of the three fused rings of the benzofuro[3,2-d]pyrimidine system are almost coplanar (r.m.s. deviation 0.021?Å). The dihedral angle between the fused ring system and the benzene ring is 1.47?(12)°. Intra-molecular and inter-molecular C-H?O hydrogen bonds together with weak C-H?? inter-actions stabilize the structure.

Project description:In the title compound, C(20)H(19)N(5)O(2), all atoms of the 1,2,3-triazolo[4,5-d]pyrimidine ring system are essentially coplanar [maximum deviation = 0.015?(2)?Å], indicating the existence of a conjugate system in which each carbon and nitrogen atom is sp(2) hybridized and ten ? electrons (three from carbon atoms and seven from nitrogen atoms) constitute an aromatic heterocycle. The ring system forms dihedral angles of 68.37?(10) and 71.57?(9)° with the phenyl rings. The crystal packing is stabilized by van der Waals inter-actions and intermolecular C-H?? interactions.

Project description:In the title compound, C(16)H(14)N(4)OS, the three fused rings of the benzothieno[3,2-d]pyrimidinone unit are essentially coplanar, the maximum deviation from the mean plane being 0.067 (3) Å.

There are two intramolecular C-H⋯O interactions.

2-Isopropyl-6-methyl-pyrimidin-4(3H)-one.

Project description:The mol-ecular structure of the title compound, C(8)H(12)N(2)O, indicates that 2-isopropyl-6-methyl-pyrimidin-4-ol (the enol-form) undergoes an enol-to-keto tautomerism during the crystallization process. The pyrimidin-4(3H)-one group is essentially planar, with a maximum deviation of 0.081 (1) Å for the O atom. In the crystal structure, symmetry-related mol-ecules are linked into centrosymmetic dimers via pairs of inter-molecular N-H⋯O hydrogen bonds, generating R(2) (2)(8) rings. These dimers are stacked along the a axis.
