- W1968164920 abstract "Reaction of 3-phenyl-10H-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indole (4) with ethyl chloroacetate gave 10-carbethoxymethyl-3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indole (3). Condensation of 3 with hydrazine hydrate gave (3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)acetylhydrazine (5). Reactions of 5 with a number of aromatic aldehydes, acetophenone, cyclohexanone and D-galactose gave the corresponding hydrazones 6-12. Condensation of 5 with acetylacetone gave the pyrazole 15. Cyclization of 5 with CS2 gave (3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)(2-thiol-1,3,4-oxadiazol-5-yl)methane (16). Reaction of 16 with ethyl chloroacetate gave the carbethoxy alkylated derivative (3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)[2-(thiocarbethoxymethyl)1,3,4-oxadiazol-5-yl]methane (17).10-Carbethoxymethyl-3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazinoDie Reaktion von 3-Phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol (4) mit Ethylchloroacetat lieferte 10-Carbethoxymethyl-3-phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol (3). Kondensation von 3 mit Hydrazinhydrat gab (3-Phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)acetylhydrazin (5), das mit einigen aromatischen Aldehyden Acetophenon, Cyclohexanon und Δ-Galactose zu den entspr. Hydrazonen 6-12 reagierte. Kondensation von 5 mit Acetylaceton gab das Pyrazol 15. Cyclisierung von 5 mit CS2 gab das (3-Phenyl-1,2,4-triazolo-[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)(2-thio-1,3,4-oxadiazol-5-yl)methan (16), dessen Reaktion mit Ethylchloroacetat gab das Carbethoxyalkyl-Derivat (3-Phenyl-1,2,4-triazolo[4′,3′:2,3][1,2,4]triazino[5,6-b]indol-10-yl)-[2-(thiocarbethoxymethyl)1,3,4-oxadiazol-5-yl]methan (17)." @default.
