Synthesis of indolo[2′,3′:5,6][1,2,4]triazino[4,3-a][1,8]- Naphthyridines and 3′-(3-phenyl-1,8-naphthyridin-2-ylamino)spiro- [3H-3, 2′-thiazolidine]-2,4′(1H)-diones as potential antibacterial agents

Condensation of 2-hydrazino-3-phenyl-1,8-naphthyridine 4 with different isatins 5 gives 2-(3-phenyl-1,8-naphthyridin-2-ylhydrazono)-2-indolinones 6, which on cyclization with POCl3 under reflux result in the formation of 7-phenylindolo[2′, 3′:
