Definitions

  • H. Kunz and co-workers have proposed the reaction of an O-pivaloyl-galactosylamine with aldehydes and a cyanide source to form the N-galactosyl ⁇ -amino nitriles (see Liebigs Ann. Chem. 1991, 649-654 and International Patent Application No. WO88/00592) .
  • the galactosylamine reagent by Kunz can be envisioned as a derivative of an "amino sugar" (which for purposes of this invention is defined as an amine-functionalized sugar molecule) where the anomeric oxygen has been replaced with a nitrogen atom and the hydroxyl groups have been protected.
  • This invention relates to the formation of an ⁇ -amino- nitrile compound by reaction of an amino sugar, a carbonyl compound, and a cyanide source.
  • amino sugar as used herein is intended to relate to sugar, or carbohydrate, molecules which contain one or more amino groups in place of the hydroxy moiety or moieties ordinarily contained as substituents thereon. It is within the contemplation of the present invention to cover both acyclic as well as cyclic sugar species. Monosaccharides, disaccharide, and polysaccharide-derived amino sugars can be utilized. Acyclic monosaccharides such as glucamine and fructamine are representative of amino sugars which can be used herein.
  • the amino sugar reagent used in the present process does not require protection of the hydroxyl groups contained therein, for example.
  • the carbonyl compound which is used herein as a second reagent is preferably a bisulfite addition product of an aldehyde having the structure RC(0)H, where R can be alkyl, aryl, alkylaryl, or arylalkyl. Preferably R is either straight chain or branched chain alkyl of from one to fourteen carbon atoms.
  • Some representative aldehydes which can be used include isobutyraldehyde, 2-ethylhexanal, and decanal. Ketones of the formula R-C(0)-R, with R being the same or different and defined as above can also be used.
  • the cyanide source is preferably an alkali metal cyanide, such as sodium cyanide.
  • the reaction of amino sugar, carbonyl compound, and cyanide source can be carried out in organic solvent, a mixed organic/aqueous solvent, or an all aqueous solvent medium.
  • the organic solvent if used, can be a water-miscible polar protic solvent (e.g., an alcohol), or a water-miscible polar aprotic solvent (e.g., tetrahydrofuran or dimethyl sulfoxide) .
  • Polar and non-polar solvents that are water immiscible e.g. , methylene chloride or toluene
  • the reaction temperature can vary widely (e.g., from about 0°C to the reflux temperature of the reaction medium, preferably 20°C to 60°C) . Stoichiometric amounts of amino sugar, carbonyl compound, and cyanide source are preferred.
  • the ⁇ -aminonitrile products derived from the process are intended as surfactants, chelants, or dispersants with the moiety derived from the amino sugar improving such properties as water solubility, biodegradability and chelation.
