Pd-Catalyzed Autotandem C–C/C–C Bond-Forming Reactions with Tosylhydrazones: Synthesis of Spirocycles with Extended π-Conjugation

07-04-2014 | Raquel Barroso; Rocío A. Valencia; María-Paz Cabal; Carlos Valdés, Organic Letters, 2014

A new Pd-catalyzed autotandem process is presented by the reaction of tosylhydrazones of cyclic ketones and 2,2′-dibromobiphenyls and related systems. The process involves cross-coupling with tosylhydrazone followed by an intramolecular Heck reaction and gives rise to spirocyclic structures. ...
