To a solution of iminophosphorane (2.0 mmol) in absolute anhydrous dichloromethane (10.0 ml), isocyanatobenzene (2.0 mmol) was added under nitrogen atmosphere at room temperature. After the reaction mixture was stirred for 3.0 h at room temperature, the iminophosphorane had disappeared (TLC monitored). The solvent was removed under reduced pressure and EtOH/petroleum ether (1:3, 15.0 ml) was added to precipitate triphenylphosphine oxide. Removal of the solvent gave
which were used directly without further purification. To a solution of in dichloromethane (10.0 ml) was added pyrrolidine (2.0 mmol). The reaction mixture was left unstirred for 6 h. The solvent was removed and anhydrous EtOH (10.0 ml) with several drops of EtONa was added. The mixture was stirred for 6–12 h at room temperature. The solution was condensed, workup and (hexane/AcOEt) gave the expected cyclic compounds in good yield. The crystals of the title compound were grown mother liquor by slowly evaporation from at room.The hydrogen atoms were placed in geometrically idealized positions with Csp2—H = 0.93Å and Csp3—H = 0.97 Å, and constrained to ride on their parent atoms with Uiso(H) set to 1.2 × Ueq(C).
Pyrimidine derivatives are very important molecules in biology and have many application in the areas of pesticide and pharmaceutical agents (Condon et al., 1993). Pyrimidine derivatives have also been developed as antiviral agents, such as AZT (azidothymidine), which is the most widely used anti-AIDS drug (Gilchrist, 1997). In order to discover further biologically active pyrimidine compounds, the title compound was synthesized, and its
was determined which is presented in this paper.In the title compound (Fig. 1) the tetrahydropyran ring adopts a twist chair conformation with S2 and C1 lying 0.451 (5) and 0.474 (5) Å, respectively, on the opposite sides of the plane formed by the rest of the ring atoms. The pyridinone unit is essentially planar with a mean deviation of 0.0497 Å; the maximum deviation of any atom from the plane is 0.0432 (14) Å for N3. The pyrimidone and the thiophene rings are almost coplanar with the dihedral angle 6.31 (15)° and the dihedral angle between the mean-planes of the phenyl ring and the pyridinone ring is 68.13 (10)°. The thiophene ring is essentially planar (max. dev. 0.024 (2) Å for C4) while the tetrahydropyrrole exhibits a C12-envelop conformation with C12 lying 0.568 (4) Å out of the plane formed by the rest of the atoms in the ring.
The bond distances and bond angles in the title compound are comparable to the corresponding distances and angles reported for a closely related compound (Xie et al., 2008). In the
adjacent molecules are linked by C–H···O hydrogen bonding interactions (Tab. 1), and form a two-dimensional network (Fig. 2).For the applications of pyrimidine derivatives as pesticides and pharmaceutical agents, see: Condon et al. (1993) and as antiviral agents, see; Gilchrist (1997). For a related structure, see: Xie et al. (2008).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Pyrimidine derivatives are very important molecules in biology and have many application in the areas of pesticide and pharmaceutical agents (Condon et al., 1993). Pyrimidine derivatives have also been developed as antiviral agents, such as AZT (azidothymidine), which is the most widely used anti-AIDS drug (Gilchrist, 1997). In order to discover further biologically active pyrimidine compounds, the title compound was synthesized, and its crystal structure was determined which is presented in this paper.
In the title compound (Fig. 1) the tetrahydropyran ring adopts a twist chair conformation with S2 and C1 lying 0.451 (5) and 0.474 (5) Å, respectively, on the opposite sides of the plane formed by the rest of the ring atoms. The pyridinone unit is essentially planar with a mean deviation of 0.0497 Å; the maximum deviation of any atom from the plane is 0.0432 (14) Å for N3. The pyrimidone and the thiophene rings are almost coplanar with the dihedral angle 6.31 (15)° and the dihedral angle between the mean-planes of the phenyl ring and the pyridinone ring is 68.13 (10)°. The thiophene ring is essentially planar (max. dev. 0.024 (2) Å for C4) while the tetrahydropyrrole exhibits a C12-envelop conformation with C12 lying 0.568 (4) Å out of the plane formed by the rest of the atoms in the ring.
The bond distances and bond angles in the title compound are comparable to the corresponding distances and angles reported for a closely related compound (Xie et al., 2008). In the crystal structure, adjacent molecules are linked by C–H···O hydrogen bonding interactions (Tab. 1), and form a two-dimensional network (Fig. 2).
