Antimalarial alkaloids, febrifugine (1) and isofebrifugine (2), were synthesized from simple achiral starting materials using tin(II)-catalyzed catalytic asymmetric aldol reaction and lanthanide-catalyzed aqueous three-component reaction as the key steps. These unambiguous total syntheses revealed that the absolute configurations of febrifugine and isofebrifugine were not (2′S, 3′R) and (2′R, 3′R)
以锡(II)催化的催化不对称醛醇醛缩合反应和镧系元素催化的三组分水溶液三步反应为关键步骤,由简单的非手性起始原料合成了抗疟原生物碱,非溴夫定(1)和异氟哌啶(2)。这些明确的总合成结果表明,如先前报道的那样,非贝氟定和异氟苯丙胺的绝对构型不是(2'S,3'R)和(2'R,3'R),而是(2'R,3'S)和(2 ',3'S)。
