synthesis of amides has been explored by using secondary alcohols, Cu(ClO4)2·6H2O as a catalyst, and trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) at ambient temperature. This method has been successfully adapted to the preparation of azides directly from their corresponding alcohols and offers excellent chemoselectivity in the formation
Aminocarbonylation of alkenyl iodides with CO and amines proceeded under heating to produce α,β-unsaturatedamides in good yields (23 examples, 71% average yield). This catalyst-free method exhibited good functional-group tolerance, and open a straightforward access to functionalized acrylamides, as illustrated by the synthesis of Ilepcimide. A hybrid radical/ionic mechanism involving chain electron transfer is
烯基碘与 CO 和胺的氨基羰基化在加热下进行,以良好的产率(23 个实例,71% 的平均产率)产生 α,β-不饱和酰胺。这种无催化剂的方法表现出良好的官能团耐受性,并打开了对官能化丙烯酰胺的直接访问,如 Ilepcimide 的合成所示。针对这种转变提出了一种涉及链式电子转移的混合自由基/离子机制。
