Oxadiazolines are bench-stable diazo precursors, which are activated under UV radiation in the presence of vinylboronic acids and aldehydes to enable a one-step three-component assembly of densely functionalized homoallylic alcohols. Substitution on all positions of the homoallylic alcohol product were achieved with high functional group tolerance. No catalyst or other additive was required to effect
恶二唑啉是稳定的重氮前体,可在
乙烯基硼酸和醛存在下在紫外线辐射下活化,以使一步反应的三组分稠密官能化均烯丙基醇组装成为可能。在高官能团耐受性的情况下,实现了在均烯丙基醇产物的所有位置上的取代。不需要催化剂或其他添加剂即可进行反应,该反应在20°C下进行40分钟。还掺入了
亚胺和
吲哚,从而获得了均
烯丙基胺。
