Latest Patents

Chi's latest patents include groundbreaking methods for preparing amides and amino acids. One of his notable inventions provides novel compounds and methods to carry out organocatalytic Michael additions of aldehydes to nitroethylene, catalyzed by a proline derivative. This process yields α-substituted-γ-nitroaldehydes and can be rendered enantioselective using a chiral pyrrolidine catalyst, resulting in Michael adducts that are nearly optically pure, with enantiomeric excesses ranging from 96% to 99%. These Michael adducts can be efficiently converted to protected γ-amino acids, which are essential for systematic conformational studies of γ-peptide foldamers.
