homologation of vinyl triflates and bromides for the synthesis of homoallylic nitro products is described. This palladium-catalyzed double coupling of nitromethane exploits the anion stabilizing and leaving group properties of nitromethane, generating the homo allyl nitro products via a tandem cross-coupling/π-allylation sequence. The resultant process provides a mild and convenient entry to nitroethylated
描述了用于合成高烯丙基硝基产物的乙烯基三氟甲磺酸酯和溴化物的双碳同源性。这种钯催化的硝基甲烷双偶联利用了硝基甲烷的阴离子稳定和离去基团特性,通过串联交叉偶联/π-烯丙基化序列生成高烯丙基硝基产物。由此产生的过程为硝基乙基化产物提供了一种温和而方便的入口,硝基乙基化产物是 β,γ-不饱和羰基化合物、高烯丙基胺和腈氧化物的通用前体。
