Copper-Catalyzed Regio- and Diastereoselective 1,3-Dipolar Cycloaddition Reactions of Glycine Imino Esters with 1-Propene-1,3-sultone
The 1,3-dipolar cycloaddition of glycine imino esters (azomethine ylide precursors) with 1-propene-1,3-sultone proceeded smoothly by using copper phosphine complexes at room temperature to give the bicyclic sultone-fused pyrrolidines as single regio- and stereoisomers in good yields. A preliminary asymmetric reaction with a chiral copper complex gave the fused sultone-pyrrolidine with excellent enantioselectivity.
