Novel dipolarophiles and dipoles in the metal-catalyzed enantioselective 1,3-clipolar cycloaddition of azomethine ylides

摘要

The catalytic asymmetric 1,3-clipolar cycloaddition of azomethine ylides constitutes one of the most powerful and atom economical methods for the enantioselective construction of pyrrolidines. This article highlights the recent developments in this area, with special focus on contributions improving the structural scope at the dipolarophile and azomethine ylide partners.
