  Preparation of cyclomanganated chalcones and their reactions with methyl acrylate and other α, β-unsaturated carbonyl compounds

  摘要：

  Chalcones [(E)-1,3-diarylprop-2-en-1-ones] react with benzyltetracarbonylmanganese under reflux in petroleum spirit to give two types of cyclomanganation products. The first, involving metallation at the alkenyl beta-carbon of the enone, are derivatives of [[1-phenyl-2-phenylcarbonyl-kappa O]ethenyl-kappa C-1]tetracarbonylmanganese, while the second type, manganated at the aryl ring ortho-carbon, are derivatives of [2-[3-phenylprop-2-en-1-onyl-kappa O]phenyl-kappa C-1]tetracarbonylmangane In general, more ''alkene-manganated'' than ''ring-manganated'' product is formed, with the ratio influenced significantly by certain substituents, e.g. a 4-CF3 substituent on the phenyl ring at C3 of the enone strongly promotes ''alkene-manganation''. in some cases there are minor by-products derived from coupling of two chalcone molecules after initial cyclomanganation. The crystal structures are reported for two such products, [2-((1S*,2R*,3S*)-1-hydroxy-1-((E)-2-(2-trifluoromethylphenyl)ethenyl)-3-(2-trifluoromethylphenyl)-6-methoxy-2-indanylcarbonyl- kappa O)-6-methoxyphenyl-kappa C-1]tetracarbonylmanganese and (1S*,4S*,5R*)-5-(4-bromobenzoyl)-1-(4-bromophenyl)-3,4-di-(4-trifluoromethylphenyl)cyclopent-2-en-1-ol.In acetonitrile under reflux, alkene-manganated chalcones react with methyl acrylate (methyl propenoate) to form derivatives of methyl (E)-4,6-diphenyl-6-oxohex-2-enoate and of 5-(2-methoxycarbonylethyl)-3,5-diphenylfuran-2-(5H)-one. The latter butenolides are not formed when the reactions are carried out in carbon tetrachloride, only the former alpha,beta-unsaturated esters. By contrast, in a few reactions studied, acrolein (propenal) and methyl vinyl ketone (but-3-en-2-one) give only the butenolide products when treated with alkene-manganated chalcones in refluxing acetonitrile. An exception is the reaction of methyl vinyl ketone with [[1 -(3,4,5-trimethoxyphenyl)-2-(4-chlorophenylcarbonyl-kappa O)]ethenyl-kappa C-1]tetracarbonylmanganese to form the cyclized product 5-acetyl-1-(4-chlorophenyl)3-(3,4,5-trimethoxyphenyl)cyclopent-2-en-1-ol.

  The synthesis and effect of fluorinated chalcone derivatives on nitric oxide production

  摘要：

  Dimethoxy- and trimethoxychalcone derivatives, with various patterns of fluorination, were synthesized and evaluated for their influence on nitric oxide production. Some of them, chalcones 1, 5, 7, 10, 11 and 17, inhibited NO production with an IC50 in the submicromolar range; 17 is especially noteworthy because of its potency (IC50 30 nM). These effects were not the consequence of a direct inhibitory action on enzyme activity but the inhibition of enzyme expression. (C) 2002 Elsevier Science Ltd. All rights reserved.
