Abstract

Formation of Indoles, Dihydroisoquinolines, and Dihydroquinolines by Ruthenium-Catalyzed Heterocyclizations. -Ru-catalyzed heterocyclization of alkynyl substituted anilines, benzamides, and benzylamines yields the title heterocycles (II), (IV) and (VI), resp., under mild conditions. The process can be extended to the sulfonamide (VI) or the isomeric substrate (IX) with similar success. -(VARELA-FERNANDEZ, A.; VARELA, J. A.; SAA*, C.; Synthesis 2012, 21, 3285-3295, http://dx.
