Abstract

A novel series of chiral phosphoric acid (CPA) catalysts based on a bioinspired aporphinol scaffold has been developed. The efficacy of these CPAs is demonstrated through enantioselective transfer hydrogenation of C2-substituted quinolines, achieving excellent enantioselectivities (93–99% enantiomeric excess). They also exhibit catalytic efficiency comparable to that of classic chiral phosphoric acids in the asymmetric Friedel–Crafts reaction and reduction of ketone. This work highlights the potential of aporphinol-based catalysts for diverse asymmetric transformations.

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.
