intermediate of the dysiherbaine tetrahydropyran core has been achieved in 11 steps and 27% overall yield. The key feature of this synthetic approach is the application of the Donohoe tethered aminohydroxylation reaction to install the amino diol and establish the four contiguous syn stereocenters on the tetrahydropyran ring.
以11个步骤完成了dysiherbaine四氢吡喃核心高级中间体的立体控制和可扩展合成,总收率达27%。该合成方法的关键特征是应用Donohoe束缚的氨基羟基化反应来安装氨基二醇并在四氢吡喃环上建立四个连续的顺式立体中心。
