Organocatalytic enantioselective pictet-spengler reactions for the syntheses of 1-substituted 1,2,3,4-tetrahydroisoquinolines

Mons, Elma,Wanner, Martin J.,Ingemann, Steen,Van Maarseveen, Jan H.,Hiemstra, Henk

, p. 7380 - 7390 (2014/09/17)

A series of 1-substituted 1,2,3,4-tetrahydroisoquinolines was prepared from N-(o-nitrophenylsulfenyl)phenylethylamines through BINOL-phosphoric acid [(R)-TRIP]-catalyzed asymmetric Pictet-Spengler reactions. The sulfenamide moiety is crucial for the rate
