SET-photosensitized reactions of α,β-enones and -ynones containing tethered α-silylamine functions are described. The processes lead to hydropyridine ring construction via pathways involving 6-endo type α-amino radical cyclizations. High degrees of regio- and stereocontrol attend these reactions.
描述了含有束缚的α-甲硅烷基胺官能团的α,β-烯酮和-炔酮的SET光敏反应。该过程通过涉及6-内基型α-氨基自由基环化的途径导致氢吡啶环的构建。高度的区域控制和立体控制参与了这些反应。
