high yields (up to 95%) under mild conditions from the reaction of trisubstituted olefins bearing different groups with nosyloxycarbamates in the presence of calcium oxide. We propose a possible explanation for the different reactivities observed between these olefins and the aminating agents. Reagent-controlled stereoselective amination reactions led to the expected products with high conversions and
在温和条件下,在氧化钙的存在下,由带有不同基团的三取代烯烃与硝基甲氧基氨基甲酸酯的反应容易以高产率(高达 95%)获得高度官能化的氮丙啶。我们对在这些烯烃和胺化剂之间观察到的不同反应性提出了可能的解释。试剂控制的立体选择性胺化反应产生具有高转化率和纯度的预期产物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
