Patents by Inventor Theodore Alexander Betley

Theodore Alexander Betley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11918984
    Abstract: Disclosed are compounds, methods, reagents, systems, and kits for the preparation and utilization of monomeric or polymeric metal-based compounds. These metal-based compounds are organometallic catalysts composed of substituted dipyrrin ligands bound to transition metals. C—H bond functionalization catalysis can be performed with the disclosed organometallic catalysts to yield C—N bonds to generate substituted bicyclic, spiro, and fused nitrogen-containing heterocycles, all common motifs in various pharmaceutical and bioactive molecules.
    Type: Grant
    Filed: September 19, 2019
    Date of Patent: March 5, 2024
    Assignee: President and Fellows of Harvard College
    Inventors: Theodore Alexander Betley, Alexandre Mikhailine, Claudia Kleinlein, Yuyang Dong, Yunjung Baek

  • Patent number: 9724682
    Abstract: The present invention provides novel synthetic methods for making acyclic secondary amines by reacting an azide with a compound bearing one or more C—H groups, catalyzed by a FeII-dipyrromethene complex. The acyclic secondary amines are thought to be formed through an intermolecular nitrene transfer. Also provided herein are methods of synthesizing protected (e.g., Boc- or Fmoc-protected) cyclic secondary amines (e.g., 5-, 6-, and 7-membered cyclic secondary amines) by reacting an azide that bears one or more C—H groups, catalyzed by a FeII-dipyrromethene complex. The protected cyclic secondary amines are thought to be formed through an intramolecular nitrene transfer and may be subsequently deprotected to yield cyclic secondary amines.
