intramolecular photoinduced cyclization of enediynes leading to aromatic compounds.
Notes: - The solvent plays a key role in the reaction efficiency and product distribution. The reversibility of the initial @P04585@ and competing radical vs ionic pathways dictate product distribution, in stark contrast to the thermal process.
- This reaction is particularly attractive in molecular biology and molecular medicine. In particular, it permits the expeditious synthesis of core synthones of great diversity.
