The acids named in the title, and also hexadeca-3,9-diynoic and eicosa-7,13-diynoic acids, which all contain acetylenic groups separated by a tetramethylene chain, have been synthesised. The methods employed involved alkylation of the NN-dimethylamide of a terminal acetylenic acid, or of an acetylenic alcohol, with final hydrolysis or oxidation, respectively. Eicosa-5,11,14-triynoic acid was prepared
合成了标题中提到的酸,以及十六烷基的3,9-二炔酸和二十碳的7,13-二炔酸,它们都含有被四亚甲基链隔开的炔基。所采用的方法涉及末端炔属酸或炔属醇的NN-二甲基酰胺的烷基化,并分别进行最终水解或氧化。Esosa-5,11,14-triynoic acid通过Osbond法将十二烷基5,11-diynoic acid的Grignard配合物与辛基-2-炔基溴化物烷基化制备。已经研究了这些炔酸的催化半氢化。
