Homoallylic amines are important building blocks for the synthesis of nitrogen-containing natural products. They are generally synthesized by addition of allyl metal compounds to imines. With the establishment of photoredox catalysis in organic chemistry, research interest in homoallylic amine syntheses via radical reactions has increased. Herein, we present a dual photoredox/nickel catalyzed regio-
高烯丙基胺是合成含氮天然产物的重要组成部分。它们通常通过将烯丙基金属化合物与亚胺加成来合成。随着有机化学中光氧化还原催化的建立,通过自由基反应合成高烯丙基胺的研究兴趣增加了。在此,我们提出了N-芳基 α-氨基酸的双光氧化还原/镍催化的区域选择性和非对映选择性烯丙基化反应。我们的方法以高产率和高合成能力产生支链高烯丙基胺在温和和氧化还原中性条件下的非对映选择性。我们反应的合成灵活性在广泛的底物范围内得到证明,其特点是具有高官能团耐受性。详细的机理研究表明,亚胺是该反应的关键中间体。
