Cascade radical reactions, initiated by cyclisation of sp3 carbon-centred radicals onto the C-atom of imines, have been used to develop a new protocol for the synthesis of a range of nitrogen heterocycles. The C-centred radical intermediates were generated from benzeneselenyl precursors using Bu3SnH. The aminyl radicals generated by cyclisation onto imines undergo further 5- or 6-exo cyclisation with
级联自由基反应是通过将sp 3碳中心自由基环化到亚胺的C原子上引发的,已被用于开发合成一系列氮杂环的新方案。使用Bu 3 SnH由苯硒基前体生成C中心自由基中间体。通过环化到亚胺上而生成的胺基与适当放置的烯烃进行进一步的5或6外环化。
