Abstract

A novel series of 2-cyclopropyl-4-thiophenyl quinoline-based mevalonolactones were synthesized from the substituted anilines by several reactions. Among them, (4R,6S)-6-[(E)-2-(2-cyclopropyl-6-fluoro-4-(4-fluoro-thiophenyl)-quinoline-3-yl)-ethenyl]-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran-2-one (1d), (4R,6S)-6-[(E)-2-(2-cyclopropyl-6-fluoro-4-(3-methoxy-thiophenyl)-quinoline-3-yl)-ethenyl]-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran-2-one (1f) and (4R,6S)-6-[(E)-2-(2-cyclopropyl-6-fluoro-4,7-di(3-methoxy-thiophenyl)-quinoline-3-yl)-ethenyl]-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran-2-one (1q) showed potent HMG-CoA reductase inhibitory activity comparable with pitavastatin.
