Chiral phosphoric-acid-catalyzed asymmetric reductions of trans-chalcones have been investigated in this work. A BINOL-derived boro-phosphate-catalyzed asymmetric transfer hydrogenation of the carbon–carbon double bond of trans-chalcone derivatives employing borane as a hydride source was realized. This methodology provides a convenient procedure to access chiral dihydrochalone derivatives in high
在这项工作中,已经研究了手性磷酸催化反式查耳酮的不对称还原。利用硼烷作为氢化物来源,实现了反式查尔酮衍生物的碳-碳双键的BINOL衍生的硼磷酸盐催化的不对称转移氢化。该方法提供了在温和条件下以高收率和高对映选择性获得手性二氢氢醌衍生物的简便方法。
