the first Grignard-type nucleophilic addition using olefinic alcohols as latent carbonyl groups, providing a higher yield of the corresponding secondary alcohol than the classical hydrazone addition to aldehydes does. A broad scope of unsaturated alcohols and hydrazones, including some complex structures, can be successfully employed in this reaction, which shows the versatility of this approach and
本文中,我们报告了基于不饱和醇的钌催化氧化还原中性α-烷基化,其基于涉及烯烃异构化(链走)和and酚的协同中继过程,该过程利用了两个效率很低的单独反应步骤之间的相互作用实现高效的整体流程。这种转化显示了-型“碳负离子”和活性质子在一锅反应中的相容性,并且同时使用烯烃醇作为潜在的羰基实现了首次格氏式亲核加成,从而提供了更高产率的相应仲醇比传统的除醛还要多。广泛的不饱和醇和,包括一些复杂的结构,可以成功地用于该反应,
