Ketones and thioesters undergo soft enolization and acylation using crude acid chlorides on treatment with MgBr2·OEt2 and i-Pr2NEt to give 1,3-diketones and β-keto thioesters, respectively. The use of crude acid chlorides adds efficiency and cost reduction by avoiding the need to purify and/or purchase them. The process is conducted in a direct fashion that does not require prior enolate formation
使用MgBr 2 ·OEt 2和i- Pr 2 NEt处理粗制酰氯后,酮和硫酯会进行软化和酰化反应,分别得到1,3-二酮和β-酮硫酯。粗制酰氯的使用避免了纯化和/或购买它们的需要,从而提高了效率并降低了成本。该方法以直接方式进行,不需要预先形成烯醇化物,从而进一步提高了其效率并使其非常容易进行。该方法适用于大规模应用。
