ABSTRACT:
The invention relates to methods for reacting (di)amines as substrates in the presence of a lysine oxidase arid a reducing agent, resulting in alcohols, diols or cyclic secondary amines. In a particular embodiment, the invention is directed to methods of preparing cyclic secondary amines suitable for ultimately synthesizing piperidine-2-carboxylic acid and proline derivatives, useful, for example as thrombin inhibitors.
