Nitro Or Nitroso Patents (Class 562/434)
  • Patent number: 8314214
    Abstract: Methods are disclosed for preparing compounds of Formula I: where R1, R3, and R4 are independently hydrogen or C1 to C4 alkyl, and R2 is: where R5 is selected from the group consisting of hydrogen and C1 to C4 alkyl, or where R6, R7 and R8 are independently hydrogen or C1 to C4 alkyl; or the esters or pharmacologically acceptable salts thereof. The methods can involve converting a suitably functionalized aniline compound to a diazonium salt (which aniline compound can be first formed by reduction of a nitrobenzene) and coupling the diazonium salt with a suitably functionalized benzene compound. The suitably functionalized aniline compound either includes a primary alcohol or aldehyde group, which is then oxidized to a carboxylic acid group, or includes a nitrile or amide group, which is hydrolyzed to a carboxylic acid group. The methods can also involve the direct coupling (via reduction of nitro groups to form an azo linkage) of suitably functionalized nitrobenzenes.

  • Patent number: 8269039
    Abstract: The invention provides novel compounds and methods to carry out organocatalytic Michael additions of aldehydes to nitroethylene catalyzed by a proline derivative to provide ?-substituted-?-nitroaldehydes. The reaction can be rendered enantioselective when a chiral pyrrolidine catalyst is used, allowing for Michael adducts in nearly optically pure form (e.g., 96-99% e.e.). The Michael adducts can bear a single substituent or dual substituents adjacent to the carbonyl. The Michael adducts can be efficiently converted to protected ?2-amino acids, which are essential for systematic conformational studies of ?-peptide foldamers.

The presumptive mechanism of action in preventing cancer cell and virus replication is through inhibition of the binding of transcription factors to zinc finger binding domains. The compounds are effective in inhibiting growth of a variety of human and animal tumor and leukemia cell lines at low concentrations.
