Herein, we report the synthesis of novel anthrone-derived Morita-Baylis-Hillman (MBH) adducts of nitroalkenes. The reaction proceeds through two consecutive SN2' additions of anthrone to MBH acetates of nitroalkenes, leading to the formation of allyl arylated anthrones. Further, we attempted a subsequent Friedel-Crafts type cyclization (Bally-Scholl reaction) to synthesize substituted benzanthrones, though with limited success.
