Merged gold and organocatalysis enables enantioselective transformations challenging for gold alone. This review highlights advancements and mechanistic insights in combined gold/organocatalyst systems for complex chemical synthesis.
Area of Science:
- Organometallic Chemistry
- Catalysis
- Asymmetric Synthesis
Background:
- Gold complexes are effective carbophilic catalysts for C-C multiple bond functionalization.
- Achieving enantioselectivity with gold catalysis is difficult due to geometric and coordination constraints.
Purpose of the Study:
- To review the recent developments in merged gold/organocatalysis for enantioselective transformations.
- To focus on the mechanistic interplay between gold catalysts and chiral organocatalysts.
Main Methods:
- Literature review of merged gold/organocatalysis systems.
- Analysis of mechanistic pathways involving gold and various chiral organocatalysts (amines, Brønsted acids, NHCs, etc.).
Main Results:
- Merged gold/organocatalysis overcomes limitations of single-catalyst systems for enantioselective reactions.
- The field has expanded significantly since its inception in 2009, utilizing diverse organocatalyst classes.
Conclusions:
- Combined gold and organocatalysis offers a powerful strategy for challenging enantioselective synthesis.
- Understanding the mechanistic synergy is crucial for designing novel catalytic systems.
