• Ruthenium nitronate complexes as tunable catalysts for olefin metathesis and other transformations

  Novel ruthenium(II) complexes were obtained as a result of a stoichiometric reaction of Grubbs’ benzylidene second generation catalysts with 3-nitropropene. These stable complexes, formally ruthenaisoxazole N-oxide derivatives, display activity in both metathesis and non-metathetic processes such as cycloisomerisation, isomerisation and transfer hydrogenation.

  新的铑(II)复合物是通过Grubbs的苯亚甲基第二代催化剂与3-硝基丙烯的化学计量反应获得的。这些稳定的复合物，形式上是铑亚异噁唑N-氧化物衍生物，在交叉烯烃聚合和非交叉过程（如环异构化、异构化和转移氢化）中均表现出活性。

  Hoveyda-type complexes have been synthesised and fully characterised. Their ability to suppress undesired double-bond migration along the carbon chain during metathesis reactions was examined. It was proved that these catalysts decrease the amounts of undesired side-products with a shifted double bond in the reaction mixture.

  已经合成并充分表征了三种新的含有醌的 Hoveyda 型配合物。检查了它们在复分解反应期间抑制不希望的双键沿碳链迁移的能力。已证明这些催化剂减少了反应混合物中具有移位双键的不需要的副产物的量。

  4-Acetoxy-2-azetidinone and (3R,4R)-4-acetoxy-3-[(1R)-1-(tert-butyldimethylsilyl)-oxyethyl]-2-azetidinone were converted into 4-alkenyloxy-, 4-(N-allyltoluene-4-sulfonamido)-, 4-(allylthio)-, and 4-alkenyl-2-azetidinone systems. In addition, 4-acetoxy-2-azetidinone and (3R,4R)-4-acetoxy-3-[(1R)-1-(tert-butyldimethylsilyl)-oxyethyl]-2-azetidinone were converted into beta-lactam dienes via sequential C-4 substitution using unsaturated alcohols, allyl mercaptan, N-allyltoluene-4-sulfonamide, and allyl(chloro)dimethylsilane followed by N-allylation. Crossed metathesis of beta-lactam alkenes with styrene partners and ring closing metathesis of beta-lactam dienes using the Schrock [(CF3)(2)MeCO](2)Mo(=CHCMe2Ph)(=NC6H3-2,6-iso-Pr-2) (1) or Grubbs Cl-2(Cy3P)(2)Ru=CHPh (2) carbenes gave diverse monocyclic and bicyclic beta-lactam systems including derivatives of 1-azabicyclo[4.2.0]octan-8-one, 1-azabicyclo[5.2.0]nonan-9-one and its 6-thia, 6-aza, and 6-oxa analogues, 7-oxa-1-azabicyclo[6.2.0]octan-10-one, 8-oxa-1-azabicyclo[7.2.0]octan-11-one, and 9-oxa-1-azabicyclo[8.2.0]octan-12-one. Ring-closing enyne metathesis and tandem ring-closing enyne and diene metathetic reactions were used to produce bicyclic beta-lactam conjugated dienes as exemplified by the conversion of (3S,4R)-(-)-3-[(1R)-(tert-butyldimethylsilyl)oxyethyl]-1-(5-oxa-oct-7-en-2-yn-1-yl)-4-(2-propenyl)-azetidin-2-one (83) into (6R,7S)-(+)-7-[(1R)-(tert-butyldimethylsilyl)oxyethyl]-3-[(2,5-dihydro)-3-furanyl]-1-azabicyclo[4.2.0]oct-3-en-8-one (98).
