Optically active hydrobenzoins are very important building blocks for further derivation of biologically active complexes, natural products, and pharmaceutical compounds. In this paper, A practical approach has been developed for asymmetric hydrogenation of benzils with Ru(OTf)(TsDPEN)(η6‐cymene) as a pre‐catalyst in methanol. Therefore, a series of chiral hydrobenzoins was synthesized in good yields
光学活性氢安息香素是进一步衍生生物活性复合物,天然产物和药物化合物的重要组成部分。在本文中,一个实用的方法已被用于与钌苯偶酰的不对称氢化显影(OTF)(TsDPEN)(η 6 -cymene)作为在甲醇中的预催化剂。因此,以良好的产率合成了一系列手性的氢安息香素,具有良好至中等的非对映选择性和良好至优异的对映选择性。
