在不直接使用任何刘易斯碱的条件下,以二乙基碘化铝为促进剂,实现了α,β-硫代丙烯酸乙酯与醛的Baylis-Hillman型反应。该反应提供了一种合成α-亚甲基-β-羟基硫酯的有效途径。
The Baylis–Hillman-type reaction of α,β-ethyl thioacrylate with aldehydes has been achieved using diethylaluminium iodide as the promoter without the direct use of any Lewis bases. The reaction provides an effective access to various α-methylene-β-hydroxy thioesters.
