Recent Advances on Transition-Metal-Catalyzed Allenamides Cyclization

Abstract

With the especial reactivity, selectivity, availability and stability, the allenamides have got more and more attention, and the reports on allenamides cyclization grow rapidly. This review gives an up-to-date overview of transition-metal-catalyzed allenamides cyclization, which are sorted by metal catalysts in eight categories of Pd, Ru, Rh, Au, Co, Ag, Pt and Ni. For most of these transformations, the plausible mechanisms are demonstrated in details. Clarification of these issues is the key point for understanding the transition-metal-catalyzed allenamides cyclization and developing new high performance methodologies for chemists.
