An aryne induced transition-metal-free and mild Sommelet–Hauser rearrangement of tertiary benzylamines for the synthesis of α-aryl amino acid derivatives in moderate to good yields is presented. Unlike the conventional Sommelet–Hauser rearrangement of ammonium salts, the methodology developed herein requires neither harsh conditions nor strong bases. Moreover, a temperature dependent switchable selectivity
提出了一种由芳烃引起的无过渡金属的温和的叔苄胺温和的Sommelet-Hauser重排,以中等至良好的产率合成α-芳基氨基酸衍生物。与传统的Sommelet-Hauser铵盐重排方法不同,本文开发的方法既不需要苛刻的条件,也不需要强碱。此外,还观察到了Sommelet–Hauser和Stevens [1,2]重排的温度依赖性可切换选择性。
