Iron-Mediated Azidomethylation or Azidotrideuteromethylation of Active Alkenes with Azidotrimethylsilane and Dimethyl Sulfoxide

by Rui Zhang, Haifei Yu, Zejiang Li, Qinqin Yan, Pan Li, Jilai Wu, Jing Qi, Menglu Jiang, Lixian Sun


A radical azidomethylation of various alkenes with azidotrimethylsilane and dimethyl sulfoxide has been achieved under mild reaction conditions, and the method efficiently introduces common and valuable azide and methyl groups into organic compounds. It offers a convenient method for preparing organic azides, which can be easily transformed into related amine derivatives and N-heterocycles. Control experiments such as capturing of the intermediate and gram-scale reactions of the developed system as well as further transformations of the products of the reaction are presented. And a free radical is involved in the reaction process.

Highly Substituted Cyclohexenes via Phosphine-Catalyzed [4+2] Annulation of Electron-deficient Dienes and Vinyl Ketones

by Junliang Zhang, Peng Chen, Junyou Zhang


A highly efficient phosphine-catalyzed [4+2] annulation of electron-deficient diene and alkyl vinyl ketone was developed for the first time, which provides an easy access to functionalized cyclohexenes. This method has the advantages of mild reaction conditions, widely functional group tolerance, high yields and transition metal free.
