Abstract
A new and green route to skeletally diverse oxo-heterocyclic architectures such as pyrano[3,4-c]chromen-2-ones and pyrano[3,4-c]quinolin-2-ones is reported via an unprecedented photocatalytic Kharasch-type cyclization/1,5-(SN″)-substitution/elimination/6π-electrocyclization/double nucleophilic substitution cascade starting from easily available heteroatom-linked 1,7-diynes and low-cost CBrCl3. During this reaction process, the full scission of carbon-halogen bonds of BrCCl3 was realized to directly build two new rings, including a lactone scaffold, using H2O as the oxygen source of the ester group.
