A tandem radical process involving conjugate addition to an activated alkene followed by allylation is reported. B-Alkylcatecholboranes, easily available via hydroboration of the corresponding alkenes, were used to generate the initial radicals. These radicals add efficiently to electrophilic alkenes such as phenyl vinyl sulfone, N-phenylmaleimide, and dialkyl fumarate. In the last step of this one-pot
据报道,串联自由基过程涉及将共轭物加到活化的烯烃中,然后进行烯丙基化。通过相应的烯烃的氢硼化容易获得的B-烷基儿茶酚硼烷被用于产生初始自由基。这些基团有效地添加到亲电烯烃中,例如苯基乙烯基砜,N-苯基马来酰亚胺和富马酸二烷基酯。在该一锅法过程的最后一步中,自由基加合物与烯丙基砜反应。整个过程可以看作是三种不同烯烃的独特且选择性的偶联。
