[1,2] and [2,3] Wittig rearrangements are competing reaction pathways, often leading to uncontrollable product distribution. We employ a single removable functional group to fulfill the dual role of attaining a reversible [2,3] and stabilizing radical intermediate for the [1,2] path to obtain both the Wittig products selectively for a broad range of substrates.
[1,2]和[2,3]维蒂希重排是竞争性反应途径,通常导致不可控制的产物分布。我们采用一个可移动的官能团来实现获得[1,2,3]路径的可逆[2,3]和稳定自由基中间体的双重作用,从而有选择地获得两种Wittig产物,可广泛用于多种基质。
