  Syntheses and Absolute Configuration Assignments of Mono- and Di-substituted Chiral Quinoline Alkaloids Obtained by Asymmetric Oxidation

  摘要：

  Mono- and di-substituted quinoline, 2-quinolone, dihydrofuroquinoline and dihydropyranoquinoline alkaloids have been synthesised with enantiomeric excess values of > 90%, via asymmetric epoxidation, or asymmetric dihydroxylation of the corresponding alkene precursors. The absolute configurations of isobalfourodine, psi-balfourodine, psi-isobalfourodine, isobalfourodinium methiodide, balfourolone, hydroxylunidine, orixine, nororixine, isopteleflorine, O-acetylisopteleflorine, O-methylhydroxylunium methiodide and hydroxylunine have been rigorously determined by a combination of circular dichroism spectroscopy, ozonolysis, and stereochemical correlation. Of these, the absolute configurations of six alkaloids were previously unknown and six were assigned incorrect configurations in the literature.
