Direct enantioselective access to 4-substituted tetrahydroquinolines by catalytic asymmetric transfer hydrogenation of quinolines.
A convenient protocol for the enantioselective synthesis of 4-substituted tetrahydroquinolines has been developed. Chiral BINOL phosphoric acids promote the reduction of a wide range of 4-substituted quinolines with Hantzsch esters with good to high levels of enantioselectivity.
متن کاملCatalytic asymmetric hydrogenation of naphthalenes.
The catalytic asymmetric hydrogenation of heteroarenes has been intensively studied during the last decade. Nowadays, various heteroaromatics, for example, indoles, pyrroles, and quinolines, can be reduced to the corresponding chiral heterocycles with high stereoselectivity through asymmetric catalysis. Glorius and co-workers recently found that a chiral N-heterocyclic carbene–ruthenium catalys...
متن کاملCatalytic Asymmetric Hydrogenation of Heteroarenes
INTRODUCTION Asymmetric hydrogenation of unsaturated organic compounds has been established as one of the most efficient methods for the preparation of chiral, non-racemic substrates. Among hydrogenation of various substrates, the asymmetric hydrogenation of heteroarenes provides a straightforward approach to a wide range of enantiomerically pure saturated heterocycles, which are subunits of ma...
متن کاملAsymmetric synthesis of tetrahydroquinolines through supramolecular organocatalysis.
Functionalized chiral tetrahydroquinolines were synthesized through supramolecular organocatalysis using quinidine-NH-thiourea 3c/L-phenylalanine 4i followed by reductive amination from the simple substrates.
متن کاملAsymmetric synthesis of functionalized 1,2,3,4-tetrahydroquinolines.
[reaction: see text] Highly enantioselective rhodium-catalyzed asymmetric hydrogenation (>98% ee) and Sharpless epoxidation (>90% ee) of o-nitrocinnamyl substrates lead to intermediates that can be transformed into tetrahydroquinoline derivatives. Starting materials are produced in high-yielding Heck reactions of an o-nitroaryl iodide and alpha-acetamidoacrylate or methyl acrylate.
