Electricity mediated [3+2]-cycloaddition ofN-sulfonylcyclopropanes with olefinsvia N-centered radical intermediates: access to cyclopentane analogs

An external oxidant free electrochemical strategy is designed towards the β-scission of strained C-C bonds in cyclopropylamine. Moreover, the mechanistic studies ascertained that the methodology encompasses the N-center radical (NCRs) route and provides access to di- or tri-substituted cyclopentane analogs.
