The invention concerns a process for the enzymatic preparation of protected di- and oligopeptides and the separation of the protective groups used. The process according to the invention enables peptides to be synthesized simply and economically and the protective group to be separated carefully. The process comprises three reaction steps: 1. Preparation of N-carbamoyl amino acid or N-carbamoyl amino acid derivatives; 2. Formation of the peptide bond between the carbamoyl-protected electrophile and nucelophile; and 3. Separation of the carbamoyl-protective group.
本发明涉及一种酶法制备受保护的二肽和寡肽以及所使用保护基的分离的方法。本发明的方法使肽能够简单、经济地合成并且可仔细分离保护基。该方法包括三个反应步骤:1.制备N-
氨基酸羰基或N-
氨基酸羰基衍
生物;2.在羰基保护的亲电体和亲核体之间形成肽键;3.分离羰基保护基。
