چکیده

The title compound, C(20)H(20)O(3), was prepared by an acyl-oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C-O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2) Å, while the C-O bond in the ester group is 1.335 (2) Å. The C-C bond lengths in the phenyl groups average 1.375 Å, while the C-C bonds in the cyclo-penta-none ring average 1.525 Å, indicating single C-C bonds in the latter.

In the crystal structure of the title compound, C(22)H(24)FN(3)O(4), the two fused rings of furo[2,3-d]pyrimidine form a dihedral angle of 0.88 (13)°. The attached benzene ring is twisted with respect to the heterocyclic pyrimidinone ring, making a dihedral angle of 75.07 (12)°. The cyclo-hexyl ring shows a distorted chair conformation. The mol-ecular structure is stabilized by intra-molecular ...

In the title compound, C(23)H(19)ClN(2)O(3)S, the central pyrimidine ring is significantly puckered, assuming almost a screw boat conformation. In addition to the usual inter-molecular C-H⋯O hydrogen bonding, short intra-molecular C-H⋯S contacts and π-π stacking inter-actions [centroid-centroid distance = 3.762 (2) Å] contribute to the crystal packing.

In the title compound, C(26)H(26)N(2)O(6)S, the benzene ring is positioned axially to the thia-zolopyrimidine ring and bis-ects it with a dihedral angle of 80.94 (7)°. The pyrimidine ring adopts a flattened boat conformation. In the crystal, pairs of bifurcated C-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis.
