Total synthesis of (±)-vinoxine: construction of the bridged pyrido[1,2-a]indole skeleton via Tf2O-mediated Bischler–Napieralski reaction and stereoselective radical cyclization

The total synthesis of (±)-vinoxine was achieved featuring the assembly of a substituted tetrahydropyrido[1,2- a ]indole skeleton through the Tf 2 O-mediated Bischler–Napieralski reaction.
