We report a new catalytic protocol for the synthesis of γ,δ−unsaturated carbonyl units from simple starting materials, allylic alcohols and alkynes, via a hydroxalkoxylation/Claisen rearrangement sequence. This new process is more efficient (higher TON and TOF) and more eco-friendly (increased mass efficiency) than the previous state-of-the-art technique. In addition, this method tolerates both terminal
我们报告了一个新的催化方案,用于通过简单的原料,烯丙基醇和炔烃通过羟基烷氧基化/克莱森重排序列合成γ,δ-不饱和羰基单元。与以前的最新技术相比,此新方法效率更高(TON和TOF更高)并且更加环保(质量效率更高)。另外,这种方法可以同时容忍末端炔烃和内部炔烃。此外,已经进行了计算研究以阐明克莱森重排是如何开始的。
