Shanbhag, Pramod published the artcileRauhut-Currier type homo- and heterocouplings involving nitroalkenes and nitrodienes, HPLC of Formula: 4230-93-7, the publication is Organic & Biomolecular Chemistry (2010), 8(21), 4867-4873, database is CAplus and MEDLINE.
Reaction of nitroalkenes R1CH:CHNO2 (R1 = 2-furyl, 2-thienyl, Ph, etc.) or nitrodienes, e.g. R2CH:CHCH:CHNO2 (R2 = Ph, 2-furyl, etc.), with Me vinyl ketone or acrylate in the presence of the imidazole-LiCl catalyst system provides Rauhut-Currier (vinylogous Morita-Baylis-Hillman) adducts R1CH:CH(NO2)CH2CH2COX (X = Me, EtO) or R2CH:CHCH:C(NO2)CH2CH2COMe in moderate yields. Under similar conditions (imidazole-hydroquinone), nitroalkenes and nitrodienes undergo self-dimerization to afford the Rauhut-Currier adducts in varying yields. An alternative self-dimerization-nitro group elimination pathway in the presence of tricyclohexylphosphine was observed with heteroaromatic nitroalkenes. A synthetically useful one-pot two step transformation of Rauhut-Currier adducts of nitroalkenes with Me vinyl ketone to 2,3-disubstituted cyclopentenones is also described.
