Selective Syntheses of Benzo[b]carbazoles and C3-Substituted Indoles via Tunable Catalytic Annulations of beta-Alkynyl Ketones with Indoles
Tunable catalytic annulation reactions of beta alkynyl ketones with indoles have been developed, enabling multiple chemical bond-forming events to selectively access skeletally diverse indole-containing heterocycles with generally good yields. Silver-catalyzed intermolecular benzannulation reaction of beta-alkynyl ketones with indoles afforded tetracyclic benzo[b]carbazoles whereas isochromen-1-yl-substituted indoles could be obtained using the same silver catalysis by lowering the reaction temperature (0 degrees C or rt). Interestingly, using Sc(OTf)(3)and AgOTf as a combined catalytic system led to the formation of C3-naphthylated indolesviaintramolecular benzannulation reaction.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 348640-06-2. Quality Control of 4-Bromo-7-azaindole.
