  摘要：

  We have developed a simple and stereoselective method for synthesizing novel dipeptide isosteres using nitrile oxide cycloaddition as a key reaction. Employing this method, we have prepared efficiently various peptidomimetics containing 2-isoxazolines and alpha-hydroxy ketomethylene dipeptide isosteres.

  N-t-butyloxycarbonyl-3-cyclohexyl-L-alanine methyl ester, previously known only as an oil, is provided in crystalline form. By addition of an organic solvent, such as methanol and/or n-hexane, to the ester in the form of an oil and cooling, crystals may be obtained. Alternatively, the ester in oily form may be seeded with a crystal produced previously. The crystalline material is of higher purity than the previously known oils, and is more useful than the oils as an intermediate in the pharmaceutical industry.
