The tobacco alkaloid (S)-anabasine was synthesized by a straightforward 4-step sequence with the catalytic enantioselective vinylogous Mannich reaction as a key step. Only 3 mol% of a structurally optimized chiral BINOL-based phosphoric acid was employed to control the absolute configuration of the natural product.
烟草生物碱(S)-anabasine的合成采用简单的四步顺序,关键步骤是催化对映体选择性乙烯基曼尼希反应。为了控制天然产物的绝对构型,只使用了 3 摩尔%的结构优化的手性 BINOL 基磷酸。
