Diastereoselective synthesis of trans-3,4-difunctionalized tetrahydroquinoline and chromane derivatives via the oxo-sulfonylation 1,7-enynes is demonstrated. The reaction involves a three-component oxidative radical polar crossover (ORPC) approach wherein vinyl carbocation intermediate undergoes nucleophilic substitution to afford corresponding keto functional group. Deprotection N-Ts group, gram-scale synthesis, other synthetic applications were illustrated. Control experiments mechanistic studies show that water acts as nucleophile in this reaction.

A photocatalytic method for the ring-closing 1,7-enyne metathesis using α-amino radical as an alkene deconstruction auxiliary is present. Preliminary mechanistic studies suggest that intramolecular 1,5-hydrogen atom transfer key to generation and β-scission of radical, while dearomatization arenes ring opening cyclopropanes are construct spirocyclic quinolin-2-ones. This approach highlights potential metathesis, providing a green, efficient, step-economical way synthesis
