protective groups by their use in a long-range nitroarene transfer cascade reaction. Using a suitably functionalized precursor, this process was used as the key step in the enantioselective totalsynthesis of the monoterpene indole alkaloids (−)-limaspermidine, (−)-kopsinilam, and (−)-kopsinine as well as the unnatural alkaloid (−)-tetra-hydrokopsifoline D.
2-硝基苯磺酰胺可通过在长程硝基芳烃转移级联反应中用作功能性保护基团。使用适当功能化的前体,该过程被用作单萜吲哚生物碱 (−)-limaspermidine、(−)-kopsinilam 和 (−)-kopsinine 以及非天然生物碱 (−)-kopsinine 的对映选择性全合成的关键步骤。 )-四氢科西林 D.
