Efficient routes to pyrazolo[3,4-b]indoles and pyrazolo[1,5-a] benzimidazoles via palladium- and copper-catalyzed intramolecular C-C and C-N bond formation

(Chemical Equation Presented) Efficient synthetic routes to pyrazolo[3,4-b]indoles and pyrazolo[1,5-a]benzimidazoles via intramolecular palladium- and copper-catalyzed cyclization of 1-aryl/1-unsubstituted 5-(2-bromoanilino)-pyrazole precursors via intram

Ring Concentration of 1,2,4-Triazepinobenzimidazol-4-ones. New Fused β-Lactams

Isolation of uncommon fused tetracyclic β-lactams 2 strongly supports a previously unconfirmed ionic mechanism for the ring concentration of nitrogen-bridged azolo-1,2,4-triazepin-3-ones in acetic anhydride.Procedure for the synthesis in good yields of substituted-pyrazolobenzimidazoles from the corresponding triazepinobenzimidazoles are reported.
