Copper-Catalyzed Intramolecular Carbocyclization/1,2-Migration Reaction of Allenols To Access Substituted 2-Sulfonyl Carbazoles
{{output}}
A copper-catalyzed intramolecular cascade carbocyclization/1,2-migration of C-2 indolyl-allenol has been achieved to construct the library of 2-sulfonyl carbazoles, which possess considerable biological significance. This modular protocol is operationally simp... ...
