the total asymmetric synthesis of valuable tropane alkaloids by catalytic stereoselective transformations is disclosed. The power of this approach is exemplified by the concise catalytic enantioselective total syntheses of (+)‐methylecgonine, (−)‐cocaine and (+)‐cocaine as well as the first catalytic asymmetric total syntheses of a cocaine C‐1 derivative and (+)‐ferruginine starting from 5‐oxo‐protected‐α
公开了通过催化立体选择性转化完全不对称合成有价值的托烷生物碱的一般策略。(+)-甲基芽子碱,(-)-可卡因和(+)-可卡因的简洁催化对映选择性总合成以及可卡因C-1衍生物和( +)-ferruginine分别仅使用两步和三步色谱纯化步骤从5-氧代保护的α,β-不饱和烯醛开始。
