ChemInform Abstract: Iminium Ion Catalysis: The Enantioselective Friedel--Crafts Alkylation--Acetalization Cascade of Naphthols with [alpha],[beta]-Unsaturated Cyclic Ketones

A combination of a cinchona alkaloid derived amine and 5-nitrosalicylic acid is an efficient catalyst system for the enantioselective synthesis of polycyclic derivatives (III), (VII), (VIII), and (X) by a Friedel--Crafts alkylation--acetalization of naphtols (I) and (VI) with cyclohexenones and cycl...
