diaryliodonium salts promoted multicomponent 1,2,3-trifunctionalization of alkynes, where both the acetylenic bond and the adjacent nonactivated propargylic C(sp3)–H bond were functionalized synergistically to generate α-arylated enones with high chemo-, regio-, and stereoselectivity. A broad spectrum of diaryliodonium salts and internal alkynes could be utilized in this protocol, and a diverse collection of
在这里,我们报告了第一个促进炔烃的多组分 1,2,3-三官能化的二芳基碘盐,其中炔键和相邻的未活化的炔丙基 C(sp 3 )-H 键被协同官能化以生成具有高化学性的 α-芳基化烯酮。 -、区域-和立体选择性。该协议可以使用广谱的二芳基碘盐和内部炔烃,并且可以从烯酮产品中详细说明高度取代和立体化学定义的线性和环状复杂结构的多样化集合。
