An efficient, highly stereocontrolled total synthesis of trichostatin A (1) has been achieved in 9 steps with 17.4 % overall yield and >99 % optical purity from readily available achiral starting materials. The key features of this synthesis include the L-proline-promoted, highly enantioselective cross-aldol reaction as a crucial step for the construction of the C-6 chiral center and the minimization
通过容易获得的非手性起始原料,可在9个步骤中完成高效,高度立体控制的曲古抑菌素A(1)的总合成,总收率为17.4%,光学纯度> 99%。该合成的关键特征包括L-脯氨酸促进的,高对映选择性的交叉羟醛缩醛反应,这是构建C-6手性中心的关键步骤,并通过将OH基团最终氧化为酮而使外消旋作用最小化在位置7。
