A practical and general Reformatsky reaction, promoted by oxidants and mediated by dimethylzinc, is described. The reaction is fast and runs at 0 °C with aldehydes and ketones, under mild reaction conditions. Preliminary results obtained for the enantioselective version show that inexpensive chiral amino alcohols could be used in the challenging formation of enantioenriched quaternary stereogenic centers
描述了一种由氧化剂促进并由二甲基锌介导的实用且通用的Reformatsky反应。该反应快速,可在温和的反应条件下于0°C与醛和酮一起运行。对映体选择性形式获得的初步结果表明,廉价的手性氨基醇可用于富挑战性地形成对映体富集的季立体异构中心。
