functionalized diheteroaryl and diaryl ketones was developed using Ru-catalysts of minimal stereogenicity. Various ketone substrates with structurally and electronically similar groups attached to the prochiral centers were reduced successfully in good to excellent enantioselectivities and yields. This protocol provides practical and efficient access to chiral diheteroarylmethanols and benzhydrols,
使用具有最小立体感的Ru催化剂开发了高度官能化的二杂芳基和二芳基酮的高度对映选择性不对称转移氢化(ATH)。在结构上和电子上相似的基团连接在前手性中心上的各种酮底物都成功地还原成良好的至优异的对映选择性和产率。该方案可提供对手性二杂芳基甲醇和苯甲醇的实用而有效的途径,它们是药物和生物活性化合物的关键中间体。
