3-Phenyl-2-(pyrrolidin-1-yl)-5,6-dihydro-8H-thio-pyrano[4',3':4,5]thieno[2,3-d]pyrimidin-4(3H)-one.

ABSTRACT: In the title compound, C(19)H(19)N(3)OS(2), the thio-pyran ring adopts a twist-chair conformation and the pyrimidinone unit is essentially planar, with a mean deviation of 0.0497 Å. The thio-phene ring is essentially planar with a maximum deviation of 0.024 (2) Å, while the pyrrolidine ring exhibits an envelope conformation. The pyrimidinone and thio-phene rings are almost coplanar, forming a dihedral angle of 6.31 (15)°, while the dihedral angle between the mean planes of the phenyl ring and the pyrimidinone ring is 68.13 (10)°. In the crystal structure, adjacent mol-ecules are linked by C-H⋯O hydrogen bonds, forming a two-dimensional network in the ac plane.
