Opticallyactivehydrobenzoins 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 asymmetrichydrogenation 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
