Organocatalytic Name Reactions Enabled by NHCs

Area of Science:

• Organic Chemistry
• Catalysis
• Medicinal Chemistry

Background:

• The tradition of naming organic reactions after their discoverers is a hallmark of chemistry.
• While less common now, historical named reactions continue to be developed and refined.
• N‑heterocyclic carbenes (NHCs) represent a significant area where this trend persists.

Purpose of the Study:

• To compile and compare historical named reactions with contemporary N‑heterocyclic carbene catalyzed processes.
• To showcase the utility of NHC catalysis in the total synthesis of biologically active compounds.
• To serve as an introductory resource for researchers new to N‑heterocyclic carbene chemistry.

Main Methods:

• Literature review and synthesis of existing knowledge on N‑heterocyclic carbene catalysis.
• Comparative analysis of historical named reactions and modern NHC-mediated transformations.
• Highlighting specific case studies of NHC applications in total synthesis.

Main Results:

• N‑heterocyclic carbene catalysis offers unique synthetic routes, often extending or paralleling established named reactions.
• NHC-catalyzed procedures are increasingly employed in complex molecule synthesis, particularly for biologically active targets.
• The review consolidates diverse NHC applications, demonstrating their versatility and impact.

Conclusions:

• N‑heterocyclic carbene chemistry provides powerful tools for synthetic chemists, bridging historical reaction classes with modern methodologies.
• The application of NHC catalysis in total synthesis underscores its importance in drug discovery and development.
• This review serves as a valuable guide for understanding and utilizing NHC chemistry.
