Synthesis of 3-((2,4-dichlorophenoxy)methyl)-1,2,4-triazolo(thiadiazoles and thiadiazines) as anti-inflammatory and molluscicidal agents.

Abstract:

:A series of fused and non fused 1,2,4-triazoles with (2,4-dichlorophenoxy) moiety are prepared utilizing 3-((2,4-dichlorophenoxy)methyl)-4-amino-4H-1,2,4-triazole-5-thiol (3). The latter on reaction with carboxylic acids, ethylchloroformate, ethylcyanoacetate and sodium nitrite gives five membered fused triazole derivatives 4a-d, 5, 6, 7 and 10, respectively. The six membered heterocycles 11, 12 and 14 are prepared by cyclization of compound 3 with phenacyl bromide, chloroacetic acid and alpha-bromoketone respectively. Most of the newly synthesized compounds were screened for their anti-inflammatory and molluscicidal activities. The compounds 4b, 4d, 11 and 14 showed potent anti-inflammatory activities in dose dependent manner while compounds 3, 4b, 8 and 10 exhibited promising molluscicidal activities.
