  • Synthesis of alpha-amino acids
    Patent number: 4375555
    Abstract: A method for synthesizing alpha amino acids proceeding through novel intermediates of the formulas:R.sub.1 R.sub.2 C(OSOCl)CN, R.sub.1 R.sub.2 C(Cl)CN and [R.sub.1 R.sub.2 C(CN)O].sub.2 SOwherein R.sub.1 and R.sub.2 are each selected from hydrogen monovalent substituted and unsubstituted hydrocarbon radicals of 1 to 12 carbon atoms. The use of these intermediates allows the synthesis steps to be exothermic and results in an overall synthesis method which is faster than the synthesis methods of the prior art.
    Type: Grant
    Filed: June 29, 1981
    Date of Patent: March 1, 1983
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventor: Jefferson W. Davis, Jr.
