Scandium-Catalyzed Intramolecular Friedel–Crafts Reactions of 2-[(2-Alkyl-1H-indol-3-yl)methylene]malonates
摘要:
We have synthesized a variety of 2-[(2-alkyl-1H-indol-3-yl)methylene]malonates and studied their scandium-catalyzed intramolecular Friedel-Crafts reactions leading to the corresponding polycyclic compounds such as indeno[1,2-b]indoles and benzo[1,2-b]carbazoles.
