Creation of Highly Asymmetric Photoreaction in Supercritical Carbon Dioxide

在这项工作中，我们研究了在超临界二氧化碳（scCO2）中的对映体分化的光反应的助溶剂（共溶剂）的效果。因此，我们阐明，我们可以提高对映体选择性加入超临界CO2相比，在传统的有机溶剂或纯超临界CO2介质中，无论是什么样的超临界CO2。此外，我们还进行了另一个非对映选择性的光反应，并阐明了我们可以获得比在有机溶剂中更高的非对映选择性，虽然反应转化率略有下降。

In this work, we examined the entrainer (co-solvent) effect to an enantiodifferentiating photoreaction in supercritical carbon dioxide (scCO2). As a result, we elucidated that we could enhance the enantioselectivity adding the entrainer in scCO2 compared to that in conventional organic solvent or pure scCO2media, irrespective of the kind of entrainer. Furthermore, we performed the other diastereoselective photoreaction in scCO2, and elucidated that we could obtain the higher diastereoselectivity than that in organic solvent, though the reaction conversion was lowered slightly.
