The present invention is to provide manufacturing intermediates which can be led to useful α-ketoamide compounds having protease-inhibiting activity extremely economically and stereoselectively, and to provide azide compounds represented by the following formula:
wherein R1 and R2 each represents alkyl group, alkenyl group, aromatic hydrocarbon group or heterocyclic group; and processes for preparing α-keto amide compound using the same.
本发明旨在提供可极其经济地、立体选择性地制备出具有
蛋白酶抑制活性的有用 α-酮酰胺化合物的中间体,并提供下式所代表的
叠氮化合物:
其中 R1 和 R2 分别代表烷基、烯基、
芳香烃基或杂环基;以及使用上述化合物制备 α-酮酰胺化合物的工艺。
