3-Isopropyl-2-p-tol-yloxy-5,6,7,8-tetra-hydro-1-benzothieno[2,3-d]pyrimidin-4(3H)-one.

ABSTRACT: In the title compound, C(20)H(22)N(2)O(2)S, the central thieno-pyrimidine ring system is essentially planar, with a maximum displacement of 0.023 (2) Å. The attached cyclo-hexene ring is disordered over two possible conformations, with an occupancy ratio of 0.776 (12):0.224 (12). Neither inter-molecular hydrogen-bonding inter-actions nor π-π stacking inter-actions are present in the crystal structure. The mol-ecular conformation and crystal packing are stabilized by three intra-molecular C-H⋯O hydrogen bonds and two C-H⋯π inter-actions.

4-Imino-2,7-dimethyl-5,6,7,8-tetra-hydro-4H-1-benzothieno[2,3-d]pyrimidin-3-amine.

Project description:In the title compound, C(12)H(16)N(4)S, the fused benzothio-phene and the pyrimidine rings are coplanar [dihedral angle = 1.61 (6)°]. Three C atoms of the cyclohexene ring (at positions 3, 6 and 7) are disordered over two sites with an occupancy ratio of 0.702 (8):0.298 (8). The cyclo-hexene ring in both the major and minor components adopts a half-chair conformation. The crystal structure is stabilized by N-H⋯N and C-H⋯N inter-actions, resulting in the formation of inversion dimers with R(2) (2)(10) and R(2) (2)(12) graph-set motifs.

7-Methyl-5,6,7,8-tetra-hydro-1-benzo-thieno[2,3-d]pyrimidin-4-amine.

Project description:In the title compound, C(11)H(13)N(3)S, two of the C atoms of the cyclo-hexene ring and the methyl group attached to it are disordered over two sets of sites in a 0.544 (2):0.456 (2) ratio. The benzothiene and pyrimidine rings are almost coplanar with an angular tilt of 2.371 (9)° between them. The thio-phene ring is essentially planar (r.m.s. deviation 0.05 Å), while the cyclo-hexene ring in both the major- and minor-occupancy conformers adopts a half-chair conformation. In the crystal structure, pairs of intermolecular N-H⋯N hydrogen bonds involving the amino groups result in centrosymmetric head-to-head dimers about inversion centres, corresponding to an R(2) (2)(8) graph-set motif. Further, N-H⋯N hydrogen bonding generates a two-dimensional hydrogen-bonded network perpendicular to the ac plane and running along the diagonal of the ac plane.
