the net result of many chiral centers is optical yields approaching 100%. Finally, we suggest a method for increasing optical yields in asymmetric induction for natural product synthesis. Where a concerted reaction is involved in the synthesis, we may study the effect of individual chiral prosthetic groups at different sites in the molecule and predict which combination will lead to the highest optical
许多手性中心的最终结果是光学产率接近 100%。最后,我们提出了一种在
天然产物合成的不对称诱导中增加光学产率的方法。在合成中涉及协同反应的情况下,我们可以研究分子中不同位点的单个手性辅基的影响,并预测哪种组合将导致最高的光学产率。因此,我们可以在不依赖偶然性的情况下系统地改进非对称归纳。
