Metal‐based catalysts: The title reaction provided the chiral adducts in high yields, excellent enantiomeric excess, and high Z/E selectivity. A combined NMR/DFT study revealed a key intermediate for the stereoselective reaction and a possible reaction mechanism (see the optimized transition‐state structure).
金属基催化剂:标题反应可提供高收率,优异的对映体过量和高Z / E 选择性的手性加合物。NMR / DFT组合研究揭示了立体选择反应的关键中间体和可能的反应机理(请参见优化的过渡态结构)。
