Polycyclo-alicyclic Ring System Patents (Class 568/941)
  • Patent number: 8586810
    Abstract: The present invention proposes a chiral diene ligand, a fabrication method thereof and applications thereof. The chiral diene ligand is a bicyclo[2.2.1] diene ligand having structural specificity and high stability, which favors the bicyclo[2.2.1] diene ligand to take part in asymmetric transformations, particularly an asymmetric addition reaction involving a metal catalyst in a basic environment. Most of the products of the reactions implemented by the chiral diene ligands of the present invention have superior optical activity. The method of the present invention comprises a first oxidation step, a saponification step, a second oxidation step, a deprotonation step, and a cross-coupling step. The chiral diene ligand of the present invention is very suitable to be used in the fabrication or synthesis of various chemicals and medical products.

  • Patent number: 5956657
    Abstract: The method provides nitro compounds at a high conversion and selectivity by nitrating substrates under comparatively mild conditions in the absence of catalysts. Organic substrates are nitrated using no catalysts or ozone, but using (1) at least one nitrogen compound selected from N.sub.2 O or NO and oxygen. It is advantageous for the nitration reaction to employ a nitrogen compound obtained by a reaction of the nitrogen compound with oxygen, particularly a nitrogen oxide comprising N.sub.2 O.sub.3 as a main component. Additionally, organic substrates are nitrated using (2) NO.sub.2. The substrates include a compound having a methine-carbon atom, and a compound having a methyl group or methylene group in an adjacent position to an aromatic ring.

  • Patent number: 5582955
    Abstract: Methods for covalently modifying surfaces of various substrates are disclosed, along with various substrates having surfaces modified by such methods. Candidate surfaces include various polymeric, siliceous, metallic, allotrophic forms of carbon, and semiconductor surfaces. The surfaces are exposed to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The nitrene covalently reacts with any of various chemical groups present on the substrate surface, thereby effecting nitrene addition of the functionalizing groups to the substrate surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface, thereby dramatically altering the chemical behavior of the surface.
