Heterocyclic Systems Containing Bridgehead Nitrogen Atom: Synthesis of Imidazo<2,1-b>-benzothiazoles and Quinoxalino<2',3':4,5>imidazo<2,1-b>benzothiazoles

2-Amino-6-t-butyl-4,5,6,7-tetrahydrobenzothiazole (II), obtained from 4-t-butylcyclohexanone and thiourea, on condensation with alpha-haloketones in benzene gives the ketones III which undergo cyclization in hot ethanol to give imidazo<2,1-b>benzothiazoles (IV).Compounds IV have also been obtained in one-step by heating II with alpha-haloketones in ethanol.II on treatment with 2,3-dichloroquinoxaline and chloroacetic acid yields in one-step quinoxalino<2',3':4,5>imidazo<2,1-b>benzothiazole (V) and imidazo<2,1-b>benzothiazol-3(2H)-one (VI), respectively.The anthelmintic, antibacterial and antifungal activities of IV and V have been evaluated.

Synthesis of 2-(Quinoxalin-2-ylamino-benzotriazolyl) Pentanedioic Derivatives as Potential Anti-Folate Agents

Anti-folate agents had a significant impact on therapeutic treatment plans for diseases such as cancer, and bacterial and parasitic infections, notably malaria. Quinoxaline derivatives showed in vitro anticancer activity and were able to inhibit both the dihydrofolate reductase and thymidylate synthase. Here, we decided to combine the chemical properties of quinoxalines and quinoxaline 1,4-dioxides with those of benzotriazole nucleus with the aim to evaluate the resulting biological properties. Two main new series, including more than 60 compounds, were prepared. In the first one, the benzotriazole moiety was linked through the nitrogen atoms 1, 2, or 3, to a glutaric acid substituent to simulate a glutamic moiety. In the second series, the glutaric acid was substituted with acetic acid moiety to evaluate the effects of steric hindrance. Here, we describe the multistep chemical processes to obtain all titled quinoxalines starting from commercially available diamines. The classical oxidation of selected quinoxalines was unsuccessful, and we have come to an independent synthetic pathway to obtain new derivatives linked to the benzotriazole moieties starting from synthons bearing N-oxide functionality.
