stereogenic center at the α-position was achieved thanks to an acid-base strategy involving an enantioselective protonation reaction as a key step. This simple and efficient protocol yields enantioenriched ketones in up to 89% ee without the need to isolate sensitive intermediates such as silyl enolates. The key role of water in this process was underlined. This one-pot sequence constitutes a useful
由于涉及对映选择性质子化反应作为关键步骤的酸碱策略,实现了在 α 位带有立体异构中心的
芳香酮的有机催化一锅顺序去外消旋化。这种简单高效的方案可产生ee高达 89% 的对映体富集酮,而无需分离敏感的中间体,如甲
硅烷基烯醇化物。强调了
水在这一过程中的关键作用。这种一锅序列构成了对先前报道的
化学驱动的氧化还原方案的有用扩展,从而增加了符合去外消旋化策略的分子面板。
