英文摘要	Over the past decade, great achievements have been made in the asymmetric hydrogenation of N-heteroaromatic compounds, which afforded diverse optically active compounds with chiral heterocyclic skeletons.[1] In contrast, the effective asymmetric hydrogenation of oxygen-and sulfur-containing heteroaromatic compounds was reported to a considerable lesser extent. Among oxygen-containing heteroaromatic compounds, isochromenyliums have received much attention as its wide applications in synthetic chemistry. However, their asymmetric potentials have been only proven recently mainly because of the lack of coordination sites on their planar structure(Hückel aromatic structure).[2] To the best of our knowledge, the transition metal-catalyzed asymmetric hydrogenation of isochromenylium compounds has not been reported so far.[3] In this presentation, we will report the asymmetric hydrogenation of a range of in situ-generated O-heteroaromatic isochromenyliums via bimetallic tandem catalysis with high yields and good to e...; Over the past decade, great achievements have been made in the asymmetric hydrogenation of N-heteroaromatic compounds, which afforded diverse optically active compounds with chiral heterocyclic skeletons.[1] In contrast, the effective asymmetric hydrogenation of oxygen-and sulfur-containing heteroaromatic compounds was reported to a considerable lesser extent.
