Enantioselective syntheses of the alkaloids (-)-aurantioclavine, (+)-amurensinine, (-)-lobeline, and (-)- and (+)-sedamine are described. The syntheses demonstrate the effectiveness of the Pd-catalyzed asymmetric oxidation of secondary alcohols in diverse contexts and the ability of this methodology to set the absolute configuration of multiple stereocenters in a single operation. The utility of an
描述了生物碱 (-)-aurantioclavine、(+)-amurensinine、(-)-lobeline 和 (-)- 和 (+)-sedamine 的对映选择性合成。合成证明了 Pd 催化的仲醇不对称氧化在不同环境中的有效性,以及该方法在单个操作中设置多个立体中心的绝对构型的能力。还描述了芳烃 CC 插入反应在访问复杂多环框架中的效用。
