PdCl2 was found to mediate the Ferrier rearrangement of broad range of substrates catalytically in neutral conditions. In this reaction, the stereoselectivity of newly formed chiral center was controlled by the hydroxyl protective groups on the starting sugar moiety and was rationally explained by the consideration of chair like conformations.
发现PdCl 2在中性条件下催化介导大范围底物的Ferrier重排。在该反应中,新形成的手性中心的立体选择性受起始糖部分上的羟基保护基控制,并通过考虑椅子样构象得到合理解释。
