2-Methylsulfanyl-1,2,4-triazolo[1,5-a]quinazoline-5(4H)-thione

چکیده
In the title compound, C10H8N4S2, comprising fused six-, six- and five-membered rings, the mol-ecule is close to being planar (r.m.s. deviation of the non-H atoms = 0.041 Å). The S-bound methyl group is folded away from the single N atom of the triazole ring and the NH group of the six-membered ring, allowing for the formation of centrosymmetric eight-membered {⋯HNCN}2 synthons in the crystal. The resulting inversion dimers are connected into supra-molecular stacks aligned along the b-axis direction by π-π inter-actions [centroid-centroid distances = 3.6531 (12) and 3.7182 (12) Å].

A series of novel ([1,2,4]triazolo[1,5-c]quinazolin-2-ylthio)carboxylic acids 2a-d and esters 3a-l were synthesized and evaluated for antimicrobial activity. Alkylation of potassium 2-thio-[1,2,4]triazolo[1,5-c]quinazoline 1 with halogenocarboxylic acids and its esters proceeded S-regioselectively. During acid catalyzed esterification of 2a-c, degradation of the pyrimidine ring was observed. Th...

In the title compounds, C7H5F3N4O, (I), and C3H3F3N4 C7H5F3N4O, (II), all of the molecular components exhibit some polarization of their molecular±electronic structures. The molecules in (I) are linked into simple C(6) chains, while in (II), the components are linked by a combination of twocentre NÐH N and NÐH O, and three-centre NÐ H (O,N) hydrogen bonds into chains containing R1(5), R2(6) and...

In the title compound, C(16)H(17)ClN(4)O(2)S, the bicyclic triazolopyrimidine ring system is nearly planar and oriented with respect to the benzene ring at a dihedral angle of 87.24 (3)°. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers; an intra-molecular C-H⋯O hydrogen bond is also present.
متن کاملBiological effects of a new set 1,2,4-triazolo[1,5-a]quinazolines on heart rate and blood pressure
BACKGROUND Several quinazoline and triazole derivatives are reported to possess a wide-range of interesting pharmacological effects. Although various triazoloquinazoline subclasses having been synthesized and studied, the preparation of 1,2,4-triazolo[1,5-a]quinazolines as antihypertensive agent is still relatively unexplored. In continuation of our earlier research, we aimed at the synthesis a...
