Remote stereocontrol in the Ireland–Claisen rearrangement using a chiral acetonide that serves as internal stereocontrol element is an effective and general method for chirality transfer from a δ-hydroxyl group in the allylic alcohol unit. This strategy circumvents the need for redundant chirality at the α-position allylic alcohol, while simultaneously producing a terminal alkene that can streamline
使用手性丙酮化合物作为内部立体控制元素的 Ireland-Claisen 重排中的远程立体控制是从烯丙醇单元中的 δ-羟基进行手性转移的有效且通用的方法。该策略避免了对 α 位烯丙醇的冗余手性的需要,同时产生可以简化合成应用和复杂分子合成计划的末端烯烃。
