equiv.), a facile and efficient protocol for the gram-scale synthesis of functionalized terminal allenes by using CuI (7.5–10 mol-%), paraformaldehyde (1.6 equiv.), and diisopropylamine (1.4 equiv.) has been developed. This method accommodates different functional groups such as hydroxy or carbonyl, and it also performed well in the synthesis of allenylamides and 2,3-butadien-1-ol.
相对于我们使用 CuI(0.5 当量)、多聚甲醛(2.5 当量)和二环己胺(1.8 当量)的原始方案,这是一种使用 CuI(7.5– 10 mol-%)、多聚甲醛(1.6 当量)和二异丙胺(1.4 当量)已被开发。该方法适应不同的官能团,如羟基或羰基,在合成丙二烯酰胺和2,3-丁二烯-1-醇方面也表现良好。
