biological activity and efficient synthesis of 3, 4-dihydropyrimidin-2-(1h)-one/thione derivatives
the present study aimed to use a method for the synthesis of some 3, 4-dihydropyrimidin-2-(1h) - ones/thiones. the study tried to answer the question whether this reaction can be performed without solvent and with new catalyst or not. to find answer to the question, we described a novel protocol for the efficient synthesis of 3, 4-dihydropyrimidin-2-(1h)-one derivatives using aromatic aldehyde,...

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کامل2-(4-Fluoroanilino)-3-(2-hydroxyethyl)quinazolin-4(3H)-one
The mol-ecular and crystal structures of the title compound, C(16)H(14)FN(3)O(2), are stabilized by intra-molecular N-H⋯O and inter-molecular O-H⋯O hydrogen bonds. The existence of non-classical intra-molecular C-H⋯N hydrogen bonds provides a dihedral angle between the fluoro-substituted benzene and pyrimidinone rings of 7.9 (1)°.
متن کامل3-(2-Aminoethyl)-2-(4-fluoroanilino)quinazolin-4(3H)-one
In the title mol-ecule, C(16)H(15)FN(4)O, the dihedral angle between the fluoro-substituted benzene ring and the pyrimidinone ring is 52.34 (7)°, while the dihedral angle between the fused benzene ring and the pyrimidinone ring is 3.30 (6)°. An intra-molecular N-H⋯N hydrogen bond may, in part, influence the conformation of the mol-ecule. In the crystal structure, inter-molecular N-H⋯N hydrogen ...
متن کامل2-(4-Chloroanilino)-3-(2-hydroxyethyl)quinazolin-4(3H)-one
In the title mol-ecule, C(16)H(14)ClN(3)O(2), the dihedral angle between the chloro-phenyl and pyrimidinone rings is 14.8 (1)°, while the dihedral angle between the fused benzene ring and the pyrimidinone ring is 3.8 (1)°. In the crystal structure, intra-molecular N-H⋯O hydrogen bonds, together with inter-molecular O-H⋯O hydrogen-bonding inter-actions, are present.
