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

Article abstract of DOI:10.1039/c7cc02788e

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 e
