of this reaction from the initial serendipitous discovery to its general synthetic scope is detailed, highlighting the roles of water, CO, and amine in the generation of a more complete catalytic cycle. The use of unsymmetrical allylic pro-nucleophiles was shown to give preferential product formation through the modulation of reaction conditions. Both (E)-cinnamyl acetate and vinyl oxirane were efficiently
钌与烯丙基亲核试剂的醛催化烯丙基化已被证明是在温和条件下形成碳-碳键的有效方法。此反应从最初的偶然发现到其一般合成范围的演变过程都进行了详细介绍,突出了水,一氧化碳和胺在更完整的催化循环生成中的作用。结果表明,使用不对称的烯丙基亲核亲核试剂可以通过调节反应条件来优先形成产物。(E)-肉桂酸乙酸酯和乙烯基环氧乙烷均有效地用于形成抗支链产物(抗/ syn最高> 20:1 )和E-线性产物(最高> 20:1 E / s )Z)分别与芳香族,α,β-不饱和和脂肪族醛形成高选择性。强调了使反应对映选择性的尝试,包括对苯甲醛高达75:25的对映富集。
