Synthesis of poly-substituted nitrobenzene derivatives from Baylis–Hillman adducts via [3+3] annulation protocol

Poly-substituted nitrobenzenes were synthesized from Baylis–Hillman adducts via the [3+3] annulation strategy as the key step. 1,3-Dinitroalkanes served as the 1,3-dinucleophilic component and the Baylis–Hillman acetates as a 1,3-dielectrophilic part.
