报道了一种无外加氧化还原剂、电还原方法, 使Morita-Baylis-Hillman (MBH)加合物实现烯丙基烷基化. 这种转变的一个关键特征是, 既不需要外部化学还原剂也不需要金属催化剂. N-烷酰氧基邻苯二甲酰亚胺(NHP)酯通过电子还原产生烷基自由基, 在烷基化过程中以高立体选择性和区域选择性展示出对烯烃取代的广泛官能团耐受性.

A redox-free, electroreductive approach to achieve allylic alkylation by employing Morita-Baylis-Hillman (MBH) adducts is reported. A critical feature of this transformation is that neither external chemical oxidants nor metal catalysts are required. Alkyl radical produced by electron reduction with N-hydroxyphthalimide (NHP) esters, displaying broad tolerance of functional groups and alkene substitution patterns in high stereoselectivity and regioselectivity.

Key words: allylic alkylation, Morita-Baylis-Hillman (MBH) adducts, electroreductive approach
