A new way of synthesizing functionalized 1,4-pentadienes by double α-addition reaction of ortho-hydroxyacetophenones to ethyl propiolate mediated by Ph3P in moderate yields is described. On the other hand, other ortho-hydroxyphenyl ketones resulted in the single α-addition products in moderate to good yields.
本研究介绍了一种新方法,即在 Ph3P 的介导下,通过原羟基苯乙酮与丙炔酸乙酯的双δ-加成反应合成官能化的 1,4-戊二烯,收率中等。另一方面,其他原羟基苯基酮也以中等至良好的收率合成了单δ-加成产物。
