A water-mediated and Rh-catalysed one-pot multi-step synthesis of chiral 1,3-diarylpropan-1-ols is presented. This protocol utilizes readily available terminal alkynes and aldehydes as reaction partners, and features mild conditions, easy operation and water as the sole solvent, thus serving as an ideal means for the efficient synthesis of chiral 1,3-diarylpropan-1-ols. Control experiments suggested
提出了一种水介导和 Rh 催化的一锅多步合成手性 1,3-二芳基丙-1-醇的方法。该方案利用现成的末端炔烃和醛作为反应伙伴,条件温和,操作简便,以水为唯一溶剂,是高效合成手性1,3-二芳基丙-1-醇的理想手段。对照实验表明,查尔酮中间体的形成以及随后的双还原过程对于反应的成功至关重要。这种催化方法可以很容易地扩大规模,用于高达 10 000 S/C 的克级合成,所得产品可用于轻松衍生各种生物活性分子。
