| Research Abstract |
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.
