  Chemoenzymatic routes to enantiomerically pure 2-azatyrosine and 2-, 3- and 4-pyridylalanine derivatives

  摘要：

  Enantiomerically pure 2-, 3- or 4-pyridylalanine (pya) and 2-azatyrosine (azatyr) are known to present various biological activities. After incorporation into appropriate peptide sequences, these heterocyclic non natural alpha-amino acids could behave as new substrates or inhibitors of elastase from Pseudomonas aeruginosa. This enzyme is known to be involved in nosocomial infections and infections related to the cystic fibrosis disease. New efficient chemoenzymatic preparations of those compounds using alpha-chymotrypsin (alpha-CT) are presented.

  involves the use of a preformed, bench‐stable Pd–N‐heterocyclic carbene pre‐catalyst bearing IHept as an ancillary ligand, and allows the coupling of various functionalized coupling partners at very low catalyst loading. Careful choice of the solvent/base system was crucial to obtain optimum catalyst performance. The pre‐catalyst was also successfully tested in the synthesis of an industrially relevant
