Quaterpyridine 1 was synthesized for the first time using palladium-catalyzed cross-coupling reactions. Its proton NMR spectrum shows that is not the natural product called nemertelline isolated from nemertine marine worms as claimed in 1976.
使用钯催化的交叉偶联反应首次合成了Quetrpyridine 1。它的质子NMR谱图表明,它不是从1976年从奈梅汀海生蠕虫中分离出来的天然产物奈默特林。
