Istrate, Florin M. Gagosz, Fabien Synthesis of Functionalized Pyrroles via Gold(I)-Catalyzed aza-Claisen-Type Rearrangement Gold(I)-catalyzed cyclization of pentenynyl allyl tosylamides allows the rapid construction of functionalized pyrroles. The concerted aza-Claisen-type mechanism induces a complete selectivity of the process and allows the easy formation of quaternary centers. pentenynyl allyl tosylamides;quaternary centers;selectivity;functionalized pyrroles;RearrangementGold;cyclization;mechanism;construction;formation;Functionalized Pyrroles;Synthesi 2007-08-02
