β-unsaturated ketones is described. Reaction of the Zhdankin azidoiodane with enones in the presence of a catalytic amount of an amine provides β-azido ketones via the formation of an electron-donor–acceptor complex. The application of this protocol is demonstrated through one-step elaborations leading to the synthesis of unprecedented classes of 1,2,3-triazoles.
描述了一种操作简单的α,β-不饱和酮的有机催化β-叠氮化。Zhdankin叠氮碘烷与烯酮在催化量的胺存在下的反应通过电子给体-受体配合物的形成提供了β-叠氮基酮。该协议的应用通过一步一步精炼来证明,该合成导致合成前所未有的1,2,3-三唑类。
