Copper-catalyzed enantioselective cycloaddition/amination cascade of azomethine imines, alkynes and O-benzoylhydroxylamines

Azomethine imines as a class of important dipoles have been widely employed in enantioselective 1,3-dipolar cycloaddition reactions. Copper-catalyzed enantioselective cycloaddition of azomethine imines with alkynes is one of the most...
