Enantioselective [4+2] Annulation to the Concise Synthesis of Chiral Dihydrocarbazoles
Summary: A highly efficient phosphine-catalyzed enantioselective [4 + 2] annulation of allenoates with 3-nitroindoles or 3-nitrobenzothiophenes has been developed. The protocol represents a unique dearomatization–aromatization process to access functionalized dihydrocarbazoles or dihydrodibenzothiop...
