Bridgehead nitrogen heterocyclic systems: Synthesis and evaluation of biological activity of 2,3-dihydrothiazolo[3?,2? :2,3]-astriazino[5,6-b] indole and quinoxalino[2?,3?:4,5] thiazolo [3,2-b]indolo[2,3-e]-astriazine and their isomeric systems
2, 3-Dihydro-6-ethyl-5H-as-triazino[5, 6-b]indole-3-thione 2, on condensation with 1, 2-dibromoethane and 2, 3-dichloroquinoxaline gives the cyclized products, 9-ethyldihydrothiazolo[3?, 2?:2, 3]-as-triazino[5, 6-b]indole hydrobromide 4 and 11-ethyl quinoxalino[2?, 3?:4, 5]thiazolo[3, 2-b]indolo[2, 3-e]-as-triazine 6 respectively and not the angular isomers, 2, 3-dihydro-9-ethyl-1H-[1, 31thiazolo[2?, 3?:3, 4]-as-triazino[5, 6-blindole hydrobromide 3 and 1-ethylquinoxalino [2?, 3?:4, 5]thiazolo[2, 3-c]indolo[2, 3-e]-as-triazine 5. The unequivocal synthesis of the latter 3 and 5 has been accomplished by reaction of 7-Ethylisatin-3-thiosemicarbazone 1 with 1, 2-dibromoethane and 2, 3-dichloroquinoxaline, respectively. The antibacterial and antifungal activity of the synthesized compounds have also been evaluated.
