Selective amine de-alkylation enables the conversion of Sommelet–Hauser rearrangement products into 2-aryl-2-bromoacetic acid derivatives. These compounds are valuable synthetic intermediates in the synthesis of α-aryl-α-amino or α-aryl-β-amino acid derivatives. The method presented herein is a formal de-N,N-dialkylation of Sommelet–Hauser rearrangement products.
选择性胺脱烷基可使Sommelet-Hauser重排产物转化为2-芳基-2-溴乙酸衍生物。这些化合物是α-芳基-α-氨基或α-芳基-β-氨基酸衍生物的合成中有价值的合成中间体。本文介绍的方法是Sommelet-Hauser重排产物的正式N-,N-二烷基化反应。
