A new route to spiroacetals is presented which relies on a tin mediated radical cyclisation. This reaction has been applied to a model for phyllanthocin construction.
提出了一种新的螺缩醛途径,该途径依赖于锡介导的自由基环化。该反应已被应用到叶绿素构建模型中。

out a study on the effect of fine-tuning of the bridging ligand on the dirhodium compound. Several dirhodium compounds were designed and synthesized. During this process, we have successfully found Rh2(5-Br-esp)2 and Rh2(5-tBu-esp)2, which are closer to the ideal geometric configuration of the dirhodium(II) compounds. Rh2(5-Br-esp)2 has been applied in the oxidation of propargyl position and Rh2(5-tBu-esp)2
