Merging Organocatalysis and Gold Catalysis—A Critical Evaluation of the Underlying Concepts

Abstract

While both organocatalysis and gold catalysis have their roots deeply entrenched in the landscape of modern organic chemistry, an exciting trend in the complementary merging of organocatalysis and especially Au(I) catalysis has emerged in the last four years. This niche area has been developing rapidly and this minireview serves to pin-point the fundamental concepts guiding reaction design in these binary catalytic systems. Moreover, the proven synthetic utility of organo/Au(I) multicatalytic systems in accessing molecular frameworks, previously a challenge to single catalytic systems, has resulted in this new concept permeating numerous areas of organocatalysis, such as primary/secondary amine, Brønsted acid, hydrogen-bonding as well as N-heterocyclic carbene (NHC) catalysis. The first detailed account of these recent developments is systematically presented.
