  • Methods of producing heteropolycycles via bis-epoxidation
    Patent number: 10231970
    Abstract: A method of synthesizing a heteropolycycle, the method involving: reacting a bisepoxide with a first heteroatom nucleophile, to obtain a mixture comprising a diol compound; and further processing, to obtain the heteropolycycle with at least two heteroatoms within its polycyclic backbone, wherein each nitrogen within the polycyclic backbone of the heteropolycycle is introduced into the polycyclic backbone via an amine nucleophile.
    Type: Grant
    Filed: September 30, 2015
    Date of Patent: March 19, 2019
    Assignee: NV Heterocycles
    Inventor: Derek Alton Lightner
  • Mixtures of heteropolycycles
