Primary Institution: University of Zürich

Hypothesis

The development of new methodologies catalyzed by late transition metals involving cycloisomerizations of strained rings can open new venues for the synthesis of structurally complex molecules.

Conclusion

Gold-catalyzed ring expansions of strained rings are now considered a mature tool for constructing molecular complexity.

Supporting Evidence

  • Gold has evolved from being considered unreactive to playing a key role in catalytic processes.
  • Gold-catalyzed transformations can activate strained ring systems, opening new research areas.
  • Chiral gold catalysts have been developed for highly stereocontrolled transformations.

Takeaway

This study shows how gold can help make complex molecules by expanding small rings in organic chemistry.

Methodology

The review summarizes recent developments in gold-catalyzed ring expansions from both synthetic and mechanistic perspectives.

Limitations

The review does not provide experimental data or specific limitations of the methodologies discussed.
