Imidate Esters (i.e., Compounds Having The Imidate Group, Hn=ch-o-, Wherein Substitution May Be Made For Hydrogen Only, Bonded Directly To Carbon, Which Carbon May Be Single Bonded To Any Atom But May Be Multiple Bonded Only To Carbon) Patents (Class 558/6)
  • Patent number: 8846899
    Abstract: Disclosed are saccharide and phosphocholine derivatives. The derivatives include azide and alkyne derivatives which form one end of a variable length carbon chain. The opposite end of the variable length carbon chain is covalently linked to the saccharide or phosphocholine. The saccharide may be, for instance, a maltoside. The alkyne and azide derivatives of the saccharides and phosphocholine may be reacted together to form amphiphilic molecules useful in cellular membrane studies and applications. By adjusting the length of the carbon chain, the biochemical and biophysical properties of the resultant 1,4-disubstituted 1,2,3-triazole compounds may be custom tailored for the intended application. Resultant molecules may form micelles, bicelle, lipid bilayers and other like structures useful in the isolation and purification of membrane bound or membrane associated proteins and biochemical components.

  • Patent number: 7705175
    Abstract: Provided is a method for producing an imide ether compound in high yield. The method is characterized in that a nitrile compound, an alcohol, and a hydrogen halide are continuously introduced into a flow reaction device comprising a mixer and a flow reactor, to be subjected to a reaction. Because a reaction proceeds in a ratio of 1:1 by a flow reactor, selectivity is improved and generation of by-products is decreased, and thus an imide ether compound can be efficiently produced.

    Abstract: Dialkyl (N-cyanoimido) carbonates are prepared in good yield in a non-aqueous solvent by a process which comprises either (a) adding a cyanogen halide at a controlled rate to a reactor containing an unsubstituted or substituted dialkyl imidocarbonate, an inorganic base and/or a trialkyl amine, or (b) by adding a trialkyl amine to a solution of the unsubstituted or substituted dialkyl imidocarbonate and a cyanogen halide. The dialkyl imidocarbonate precursors are prepared by using a stoichiometric ratio (2:1) of alcohol to cyanogen halide in the presence of an acid acceptor and in a non-aqueous solvent.Dialkyl (N-cyanoimido)carbonates are useful as intermediates for pesticides and pharmaceuticals.

  • Patent number: 5091560
    Abstract: A method for synthesizing an acyloxycarboxylic acid by providing a reaction chamber, establishing sources of an .alpha.-hydroxycarboxylic acid and an acid chloride, and repeatedly contacting substantially equal molar amounts of the .alpha.-hydroxycarboxylic acid and the acid chloride within the reaction chamber. The acyloxycarboxylic acid so synthesized is useful as a starting material for conversion to various esters which, when placed in aqueous solution with a source of hydrogen peroxide, result in a peracid and are useful for bleaching applications.
