چکیده
In the title compound, C(19)H(15)FN(4)S(2), the mean plane of the thia-zolopyrimidine makes a dihedral angle of 77.6 (1)° with the attached phenyl ring. The crystal packing is stabilized by inter-molecular C-H⋯N hydrogen bonds and weak C-H-π stacking inter-actions.

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(24)H(22)N(2)O(4)S, the central pyrimidine ring is significantly puckered, assuming a conformation inter-mediate between a boat and a screw boat. The nearly planar thia-zole ring (r.m.s. deviation = 0.0258 Å) is fused with the pyriamidine ring, making a dihedral angle of 9.83 (7)°. The carboxyl group is in an extended conformation with an anti-periplanar orientation with...

4,6-Diamino-1H-pyrimidine-2-thione (1) was used for the preparation of pyrimidine derivatives 2-5. Compound 5 was cyclized to produce pyrimido[2,1-b][1,3]thiazine derivative 6 which was condensed with p-chlorobenzaldehyde to give compound 7. The latter compound was reacted with hydroxylamine to give isoxazolo[4,5-d]thiazino[2,3-a]pyrimidine 8. Compound 8b was treated with 2-chloroethyl methyl e...
