Nitroalkane benzannulation
= Nitroalkane benzannulation
A nitroalkane <carbon> can join the two ends of a five-<carbon> conjugated <ketone> framework. <carbon>–<carbon> bond formation, <thiolate> displacement and <nitrite> elimination can build a substituted <phenol>. The nitro-bearing <carbon>, rather than the nitro <nitrogen>, enters the <aromatic ring>.
