Abstract:

Catalytic enantioselective 1,3-dipolar cycloadditions (1,3-DC) involving a metalloazomethine ylide have been extensively studied since 2002. Silver(I) and copper(I)-catalyzed cycloadditions offer excellent complementary results in terms of diastereo- and enantioselections and are the most frequently employed metals nowadays. Spite of the numerous published gold(III)-catalyzed processes, the diverse range of transformations developed by gold(I) complexes have demonstrated particular interest as catalysts. Gold(I) complexes catalyze reactions under very mild conditions giving, wide functional group compatibility and high efficiency.
