一个有效的协议描述的生成和原位Diels-Alder捕获的酰基亚硝基衍生物。在此过程中,氧肟酸的氧化是有效地催化二铑(II)己内酰胺与叔丁基过氧化氢(TBHP)在二烯的存在下,在室温下。使用这种方法,我们得到了各种杂Diels-桤木环加合物的产率高达96%,在0.1摩尔%的催化剂负载。
An effective protocol is described for the generation and in situ Diels-Alder trapping of acylnitroso derivatives. In this procedure, the oxidation of hydroxamic acid is efficiently catalyzed by dirhodium(II) caprolactamate with tert-butyl hydroperoxide (TBHP) in the presence of dienes at room temperature. Using this approach we obtained a variety of hetero-Diels-Alder cycloadducts in yields of up to 96% at 0.1 mol% catalyst loading.
