• Enantioselective synthesis method of 4-aminoalcoholquinoline derivatives and the use

  Mefloquine derivatives, contrary to chloroquine derivatives have not been widely studied to date. Consequently, mefloquine and its derivatives still remain very attractive synthetic targets. Although mefloquine is usually used clinically as a racemic mixture, some studies have shown that its (+)-enantiomer is more potent than the (-)-enantiomer. Moreover, the (-)-enantiomer is responsible for side effects due to reaction with the central nervous system adenosine receptors, while the (+)-enantiomer does no bind at this binding site. Recently, different libraries of racemate 4-aminoalcoholquinolines showed interesting anti-malarial activities. Herein, the present invention describes an enantiopure synthetic and straightforward route to prepare pure enantiomer 4-aminoalcoholquinoline derivatives through the 4-oxirane key-intermediate. A regioselective SN2 ring opening of this epoxide, by diverse amines, allows to obtain the corresponding (R) or (S) 4-aminoquinolines with good yields and enantiomeric excesses generally superior to 92%. The reported methodology appears suitable for the synthesis of a large number of pure enantiomer 4-aminoalcoholquinoline derivatives.

  梅氟喹诺酮衍生物与氯喹诺酮衍生物相比，迄今为止尚未广泛研究。因此，梅氟喹诺酮及其衍生物仍然是非常有吸引力的合成目标。虽然梅氟喹诺酮通常作为外消旋混合物在临床上使用，但一些研究表明其（+）-对映体比（-）-对映体更有效。此外，（-）-对映体由于与中枢神经系统腺苷受体的反应而导致副作用，而（+）-对映体则不会在该结合位点结合。最近，不同的外消旋4-氨基醇喹啉库显示出有趣的抗疟活性。在此，本发明描述了一种对映纯的合成和直接的途径，通过4-环氧丙烷关键中间体制备纯对映体4-氨基醇喹啉衍生物。通过多种胺的区域选择性SN2环开放该环氧化物，可以获得相应的（R）或（S）4-氨基喹啉，并且收率和对映体过量通常高于92％。所报告的方法适用于合成大量对映纯的4-氨基醇喹啉衍生物。
