this method, primary and secondary alkyl groups are introduced adjacent to a ketone carbonyl under mild reaction conditions and in good yield. Cyclic, acyclic, aromatic, and aliphatic α-chloroketones are suitable substrates. Optically active α-chloroketones are converted to optically active products. The reaction was found to proceed stereospecifically with inversion of stereochemistry. The reaction
描述了由 Cu(acac)2 催化的烷基卤化锌与 α-氯酮的交叉偶联。使用这种方法,伯和仲烷基在温和的反应条件下以良好的收率与酮羰基相邻引入。环状、无环、芳香族和脂肪族 α-氯酮是合适的底物。旋光α-氯酮转化为旋光产物。发现反应立体定向地进行,立体化学反转。建议通过用有机铜、-镁或-锌物种的烷基直接取代氯化物来发生反应。
