A total synthesis of Koninginin A and its diastereoisomer starting from L-(+) tartaric acid is described. The key steps involved the Pd catalyzed cross-coupling of alkylboron with vinyl triflate and the 1O2 addition to diene. This study not only corrected the relative configuration of Koninginin A, but also assigned its absolute configuration as 1S, 4R, 5S, 6S, 9S, 10S.
描述了从L-(+)酒石酸开始进行的Koninginin A及其非对映异构体的全合成。关键步骤涉及Pd催化的烷基硼与三氟甲磺酸乙烯酯的交叉偶联以及1 O 2与二烯的加成反应。这项研究不仅纠正了Koninginin A的相对构型,而且将其绝对构型指定为1S,4R,5S,6S,9S,10S。
