There is provided a novel process for the preparation of a dipeptide represented by the formula: ##STR1## wherein Ar represents an aromatic group; R.sup.1 represents a hydrogen atom, an alkyl group or an aryl group; R.sup.2 represents a hydrogen atom, an alkyl group or an aromatic group; Y represents a hydroxy group, an amino group or an acylamino group, which comprises subjecting a .beta.-lactam compound represented by the formula: ##STR2## wherein Ar, R.sup.1 and R.sup.2 have the same meanings as defined above, and X represents a hydroxy group, an amino group or an acylamino group, an azido group or a benzyloxy group, to hydrogenolysis in the presence of a catalyst. The process can be practiced without any complicated procedure as seen in the conventional processes for the preparation of peptides.
提供了一种新型的制备二肽的方法,其化学式表示为:其中Ar代表芳香基团;R.sup.1代表氢原子、烷基或芳基;R.sup.2代表氢原子、烷基或芳基;Y代表羟基、氨基或酰胺基,该方法包括将β-内酰胺化合物进行氢解反应,该化合物的化学式表示为:其中Ar、R.sup.1和R.sup.2的含义与上文定义相同,X代表羟基、氨基或酰胺基、叠氮基或苄氧基,反应在催化剂存在下进行。该方法可以在制备肽的传统过程中不需要复杂的步骤。
