homologation of carbon dioxide with stable, (enantiopure) magnesium carbenoids constitutes a valuable method for preparing α‐halo acid derivatives. The tactic features a high level of chemocontrol, thus enabling the synthesis of variously functionalized analogues. The flexibility to generate magnesium carbenoids through sulfoxide‐, halogen‐ or proton‐ Mg exchange accounts for the wide scope of the reaction.
二氧化碳与稳定的(对映纯)镁类胡萝卜素的同系物构成制备α-卤代酸衍生物的一种有价值的方法。该策略具有高水平的化学控制功能,因此可以合成各种功能化的类似物。通过亚砜,卤素或质子镁交换生成镁类胡萝卜素的灵活性,说明了反应的广泛性。
