ChemInform Abstract: Convenient Synthesis of Tetrahydro-γ-carbolines and Tetrahydroquinolines Through a Chemo- and Regioselectivity Switch by a Broensted Acid Catalyzed, One-Pot, Multicomponent Reaction.
N-Protected 2-vinylindoles react with aromatic aldehydes and anilines to give carboline products, whereas N-unprotected 2-vinylindoles afford under the same conditions tetrahydroquinoline products almost exc...
