  Asymmetric Hydrogenation of N-Sulfonylated-α-dehydroamino Acids:  Toward the Synthesis of an Anthrax Lethal Factor Inhibitor

  摘要：

  [GRAPHIC]A novel and highly enantioselective Ru-catalyzed hydrogenation of N-sulfonylated-alpha-dehydroamino acids has been discovered and demonstrated in the synthesis of an anthrax lethal factor inhibitor (LFI). Herein, this methodology is used to prepare N-sulfonylated amino acids in up to 98% ee. This unprecedented hydrogenation uses a chiral Ru catalyst rather than Rh as typical for acylated dehydroamino acids and esters, and this work reports the first asymmetric hydrogenation of a tetrasubstituted dehydroamino acid derivative using a Ru catalyst.

  This invention relates to a process for preparing optically active α-amino acid substrates which are used to make potent lethal factor (LF) inhibitors for the treatment of anthrax. This invention further relates to a process for synthesis of potent LF-inhibitors for the treatment of anthrax. Specifically, the invention concerns a novel, high-yielding and highly enantioselective asymmetric hydrogenation reaction of a tetrasubstituted ene-sulfonamide acid or ester.
