摘要

Protease catalysed hydrolysis of N-Boc-amino acid esters allows us to obtain N-Boc l-acids and d-esters of amino butanoic acid, nor-leucine, nor-valine, leucine and t-leucine in excellent ee. The reaction occurs in short reaction times and high concentrations. When a biphasic system (buffer–MTBE) is employed, a strong solvent effect is observed. This method could be of significance for the preparation of dt-leucine, for which a practical ...
