A new method for the synthesis of conjugated silyl nitronates from nitroalkenes is described. The procedure has wide substrate scope and is compatible with in situ generation of the substrates from 2-nitroalcohols or 2-chloro-nitroalkanes. A cascade transformation to give 3,4,5,6-tetrahydropyridine N-oxide derivatives was disclosed.
描述了一种从硝基烯烃合成共轭硅烷基磺酸盐的新方法。该方法具有广泛的底物范围,并且与由2-硝基醇或2-氯-硝基烷烃原位生成底物兼容。公开了一种级联转化,得到3,4,5,6-四氢吡啶N-氧化物衍生物。
