  Disclosed are processes for the preparation of enantiomerically-enriched cyclopropylalanine derivatives by the hydrogenation of certain enamides in the presence of a catalyst comprising a transition metal and a substantially enantiomerically-pure bis-phosphine catalyst and certain novel enamide ester compounds which are intermediates in the processes. The processes include novel 2-step and 3-step processes for the preparation of enantiomerically-enriched cyclopropylalanine derivatives. The two-step process comprises the steps of reacting cyclopropanecarboxaldehyde with a substituted phosphorylglycine to afford an enamide ester which then is hydrogenated in the presence of a catalyst comprising a transition metal and a substantially enantiomerically-pure bis-phosphine catalyst. The three-step process comprises the steps of forming an azlactone from an N-acylglycine and cyclopropanecarboxaldehyde, converting the azlactone to the aforesaid enamide which then is hydrogenated in the presence of a catalyst comprising a transition metal and a substantially enantiomerically-pure bis-phosphine catalyst.

  本发明公开了在由过渡金属和对映体纯度很高的双膦催化剂组成的催化剂存在下，通过氢化某些烯酰胺制备对映体富集的环丙基丙氨酸衍生物的工艺，以及作为工艺中间体的某些新型烯酰胺酯化合物。这些工艺包括用于制备对映体富集的环丙基丙氨酸衍生物的新型两步法和三步法工艺。两步法包括环丙基甲醛与取代的磷酰甘氨酸反应生成烯酰胺酯，然后在由过渡金属和对映体纯度很高的双膦催化剂组成的催化剂存在下进行氢化反应。该三步法包括以下步骤：由 N-酰基甘氨酸和环丙烷甲醛形成氮内酯，将氮内酯转化为上述烯酰胺，然后在由过渡金属和对映体纯度很高的双膦催化剂组成的催化剂存在下进行氢化。
