A zerovalent copper- and cobalt-catalyzed direct coupling of the sp(3) α-carbon of alcohols with alkenes and hydroperoxides was developed in which the hydroperoxides acted as radical initiator and then coupling partner. 1,3-Enynes and vinylarenes underwent alkylation-peroxidation to give β-peroxy alcohols and β-hydroxyketones correspondingly with excellent functional group tolerance. The resulting
开发了一种零价铜和钴催化的醇的 sp(3) α-碳与烯烃和氢过氧化物的直接偶联,其中氢过氧化物作为自由基引发剂,然后作为偶联伙伴。1,3-烯炔和乙烯基芳烃经过烷基化-过氧化反应得到具有优异官能团耐受性的β-过氧醇和β-羟基酮。所得的 β-过氧醇可以进一步转化为 β-羟基炔酮和炔丙基 1,3-二醇。
