Cobalt(III)-catalyzed allylation of 1,3-dicarbonyl compounds has been reported with in situ generated allyl reagents from alkenes and dimethyl sulfoxide (DMSO). This novel protocol enables a high regio- and stereoselective access for a broad range of allyl 1,3-dicarbonyl compounds. In the transformation, DMSO plays the role of a C1 source, and it incorporates with alkenes to form the allyl reagent
钴 (III) 催化的 1,3-二羰基化合物的烯丙基化已被报道,原位生成烯丙基试剂从烯烃和二甲基亚砜 (DMSO)。这种新颖的协议能够对范围广泛的烯丙基 1,3-二羰基化合物进行高区域和立体选择性访问。在转化中,DMSO起C1源的作用,与烯烃结合形成烯丙基试剂烯丙基甲基硫醚。此外,还提出了一个多步骤途径来合理化机制研究,包括银介导的偶联、Co(III) 催化的 π-烯丙基化和分子间亲核取代。
