In this study we demonstrate that the combination of bis(tert‐butylcarbonyloxy)iodobenzene and lithium azide in acetonitrile allows the diazidation of various enamide substrates. The azido‐oxyamination of the same substrates can be carried out in the presence of 2,2,6,6‐tetramethylpiperidine N‐oxide (TEMPO). Control experiments strongly suggest that this latter process occurs through a shift in nature
在这项研究中,我们证明了双(叔丁基羰基氧基)碘代苯和叠氮化锂在乙腈中的组合可以使各种酰胺基被重氮化。相同底物的叠氮基氧化可在2,2,6,6-四甲基哌啶N-氧化物(TEMPO)存在下进行。对照实验强烈表明,后一种过程是通过原位生成的亲电子物种从自由基转变为阳离子而发生的。最后,还通过对其进行各种选择性反应来评估合成的新化合物的多功能性。
