Abstract Some para- and meta -substituted nitro-2-phenylindolizines were prepared and tested as potential antimicrobial agents. The syntheses were accomplished via the Chichibabin-Stepanow synthesis, using the properly substituted α -picoline and phenacyl bromides followed by direct nitration.

disulfide has been described. A series of indolizine-dithiocarbamate derivatives were easily accessed in moderate to good yields with a broad scope. In addition, imidazo[1,2-a]pyridines were also well tolerated to afford diverse imidazoheterocycle-dithiocarbamate products, which are expected to be utilized for drug discovery. Of note, the reaction could be readily scaled up, and shows its practical value in

A simple and efficient mechanochemical-induced approach for the synthesis of 1,2-diketoindolizine derivatives has been developed. BaTiO3 was used as the piezoelectric material in this transformation. This method features no usage of solvent, simple experimental operation, scalable potential, and high conversion efficiency, which make it attractive and practical.

Anhydrous AlCl3-mediated heteroarylation of various arenes and heteroarenes with 2,4-dichloro-quinazoline () and 4-chloroquinoline () afforded exclusively 4-aryl/heteroarylquinazolines () and 4-aryl/heteroarylquinolines (), respectively. Compared with the available synthetic protocols, aluminumchloride induced CC bond formation is direct and convenient to access bis-(hetero)aryl quinazolines and quinolines
