Diastereoselective Gold‐Catalyzed Cycloisomerizations of Ene‐Ynamides

Abstract

Around they go: 1,6-Ene-ynamides undergo highly diastereoselective gold-catalyzed cycloisomerizations that lead to functionalized cyclobutanones or carbonyl compounds with a 2-azabicyclo[3.1.0]hexane subunit, depending on the substitution pattern (Ts=p-toluenesulfonyl).
