Abstract

The asymmetric trans-selective hydrogenation of arenes has long been a significant challenge. In this work, we were able to control the trans/cis selectivity in ruthenium-catalyzed asymmetric hydrogenation of 2,3-disubstituted quinoxalines by varying the catalyst counteranion. Using density functional theory calculations, we investigated the weak interactions─such as CH/π and hydrogen bonding─among the counteranion, the catalyst framework, and the substrate, elucidating the fundamental influence of counteranions on trans/cis selectivity in the asymmetric hydrogenation of quinoxalines.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
