A Chemo- and Regioselective Tandem [3+2]Heteroannulation {Strategy|Technique|Method|Approach|Tactic} for Carbazole Synthesis: Synergizing Two Mechanistically Distinct Bond-Forming Processes
A modular {approach|method|strategy} to prepare tri- and tetracyclic carbazoles by a sequential heteroannulation is described. {First|Initial|Very first|1st|Initially}, op-timization of a Pd-catalyzed Buchwald-Hartwig amination followed by C/N-arylation {in a|inside a|within a}…
