Reaction of acetylides with aldehydes to form but-2-yne-1,4-diols, followed by triple bond reduction and oxidation of the hydroxyl groups, gives 1,4-diketones; these react with vinyllithium, and the resulting diols undergo ring-closing metathesis to form 2-cyclohexene-1,4-diols. Dehydration, usually by acid treatment, then gives benzenes carrying substituents in a 1,4 relationship. Use of substituted
乙炔化物与醛反应形成丁-2-炔-1,4-二醇,然后进行三键还原和羟基氧化,生成1,4-二酮;它们与乙烯基锂反应,所得的二醇进行闭环复分解反应,形成2-环己烯-1,4-二醇。通常通过酸处理进行脱水,然后得到带有1,4关系的取代基的苯。取代的乙烯基锂的使用在最终的苯环上提供了进一步的取代。该方法可以应用于C 5-芳基碳水化合物的合成。
