A process for producing an enyne derivative, and intermediate, which is useful for preparing compounds showing strong inhibiting activities against squalane.epoxidase of Eumycetes and strong anti-cholesterol activities. The process comprises reacting a compound of the formula: Z--CH.sub.2 --CH.dbd.CH--W [I] wherein W is a halogen atom, and Z is a leaving group, with an amine in the presence of a base, if necessary, to obtain a compound of the formula: ##STR1## then reacting an acetylene derivative to this compound in the presence of a palladium catalyst, to obtain a compound of the formula: ##STR2## and, if necessary, N-alkylating this compound.
生产烯烃衍生物的过程,以及中间体,该中间体对制备显示强抑制Eumycetes角鲨烷环氧化酶和强抗胆固醇活性的化合物很有用。该过程包括在碱存在的情况下,将具有以下式的化合物:Z--CH.sub.2 --CH.dbd.CH--W [I](其中W是卤素原子,Z是离去基团)与胺反应,以获得具有以下式的化合物:##STR1## 然后在钯催化剂存在下将乙炔衍生物与该化合物反应,以获得具有以下式的化合物:##STR2## 并在必要时对该化合物进行N-烷基化。
