One-pot enyne metathesis/Diels-Alder/oxidation to six-membered silacycles with a multi-ring core: discovery of novel fluorophores

Polycyclic compounds containing a six-membered silacycle are important. However, we have limited knowledge of the nature of these six-membered silacycles because methodologies for their synthesis remain under-developed. Here, we have developed a one-pot enyne metathesis/Diels-Alder/oxidation methodology for the synthesis of six-membered silacycles. Some of these compounds are novel fluorophores.
