Cu(I)-catalyzed highly exo-selective and enantioselective [3 + 2] cycloaddition of azomethine ylides with acrylates
Abstract
[reaction: see text] A novel Cu(I)-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with acrylates has been developed. Up to 98/2 exo/endo selectivity and up to 98% enantiomeric excess have been achieved.
