  Stereoselective construction of carbocycles and heterocycles via cascade reactions involving curcumins and nitroalkenes

  摘要：

  The reaction of curcumins with nitroalkenes has been investigated for the first time. Highly functionalized cyclohexanones possessing three contiguous chiral centers with complete diastereoselectivity have been synthesized through an inter-intramolecular double Michael reaction involving curcumin and nitroalkene under extremely simple experimental conditions (K2CO3 in aqueous THF). Under identical conditions, curcumins react with alpha-bromonitroalkenes to afford dihydrofurans through an intermolecular Michael addition-intramolecular nucleophilic substitution (O-alkylation), which is analogous to an 'interrupted' Feist-Benary reaction. These novel transformations of curcumins empower us to expand the repertoire of curcumin based therapeutics. (C) 2010 Elsevier Ltd. All rights reserved.

  Synthesizing synthons: The highly enantioselective title reaction is described. It employs catalytic amounts of N‐heterocyclic carbene precursors and transforms a broad range of nitroalkenes, such as nitrodienes, nitroenynes, and nitrostyrenes, through reaction with a broad range of enals, into δ‐nitroesters via homoenolate intermediates (see scheme).

  using traditional alkylation methods under basic conditions. The approach enables a highly stereoselective synthesis of quaternary (thio)oxindoles via a formal allylation-asymmetric Michael addition sequence. These adducts are versatile synthons for spirocyclic (thio)oxindoles. Initial biological studies reveal that chiral thiooxindoles show promising antiproliferation activity that is better than that

  Nitroethylenes possessing aryl, heteroaryl, and alkyl substituents at the beta-position as well as delta-substituted nitrobutadienes undergo facile aminoalkylation at the alpha-position upon treatment with formaldehyde and a secondary amine in the presence of imidazole and trifluoroacetic acid to afford alpha-aminoalkylated nitroalkenes and nitrodienes in good to excellent yield and stereoselectivity.
