An enantioselective Overman 3,3-sigmatropic rearrangement on a quinuclidine skeleton was developed for the pilot-plant synthesis of a glycine transporter 1 inhibitor. The first stereocenter was produced by a Ru-catalyzed asymmetric transfer hydrogenation process followed by chirality transfer using the Overman rearrangement. The second stereocenter was generated by a diastereoselective hydrogenation
在奎宁环骨架上开发了对映选择性的Overman3,3-σ重排用于甘氨酸转运蛋白1抑制剂的中试植物合成。第一个立体中心是通过Ru催化的不对称转移氢化过程,然后使用Overman重排进行手性转移而产生的。第二立体中心是通过非对映选择性氢化反应产生的。
