A simple process for producing ν-coelenterazine compounds has been desired. The invention provides a process for producing a ν-coelenterazine compound represented by general formula (II) which comprises (1) the step of reacting a compound represented by general formula (VIII) with a methyltriphenylphosphonium salt in the presence of a base to give a compound represented by general formula (IX), (2) the step of performing a ring-closing metathesis reaction on any one selected from the group consisting of the compound represented by general formula (IX) and a compound represented by general formula (X) which is the compound represented by general formula (IX) wherein the amino is protected with R

to give a ν-coelenteramine compound represented by general formula (XIV), and (3) the step of reacting the compound represented by general formula (XIV) with a compound represented by general formula (XV) to give the compound represented by general formula (II).
生产ν-光珊瑚蛋白酶素化合物的简单过程一直是人们所期望的。本发明提供了一种生产由通式(II)表示的ν-光珊瑚蛋白酶素化合物的方法,该方法包括以下步骤:(1)在碱的存在下,将由通式(VIII)表示的化合物与甲基三苯基膦盐反应,得到由通式(IX)表示的化合物;(2)在由通式(IX)表示的化合物和由R5保护的通式(X)表示的化合物(其中氨基被保护)中选择任意一个化合物,进行环闭合的交换反应,然后去除R4和R5(如果有的话),得到由通式(XIV)表示的ν-光珊瑚蛋白酶胺化合物;(3)将由通式(XIV)表示的化合物与由通式(XV)表示的化合物反应,得到由通式(II)表示的化合物。
