A Selectfluor-mediated approach for the synthesis of β-acyl allyl sulfones/β-acyl allyl benzotriazoles with excellent atom economy from readily available acetophenones/aryl acetylenes, aryl sulfinates/benzotriazoles, and dimethyl sulfoxide (DMSO) is described. In this protocol, DMSO acts as a dual-carbon synthon, resulting in a transition-metal-free construction of two C–C and one C–S or two C–C and
描述了一种 Selectfluor 介导的方法,用于从容易获得的苯乙酮/芳基乙炔、芳基亚磺酸盐/苯并三唑和二甲基亚砜 (DMSO) 合成具有优异原子经济性的 β-酰基烯丙基砜/β-酰基烯丙基苯并三唑。在该协议中,DMSO 充当双碳合成子,从而在一锅中形成两个 C-C 和一个 C-S 或两个 C-C 和一个 C-N 键的无过渡金属结构。这种方法被扩展以产生化学上多样化的化合物。此外,β-酰基烯丙基砜/β-酰基烯丙基苯并三唑由乙炔代替苯乙酮制备。
