carboxylic ortho esters could be used as an alkylating agent in the reductive alkylation of amines. A variety of amines, including amino acid esters, were alkylated affording mono‐alkylated products with high selectivity in practical to high yields using standard heterogeneous catalysts. By applying acyclic ortho esters alkylation was completed at room temperature.
我们首次证明了羧酸原酸酯可以在胺的还原烷基化中用作烷基化剂。使用标准的多相催化剂,将多种胺(包括氨基酸酯)进行烷基化,从而以高产率实际可行地以高选择性生成单烷基化产物。通过施加无环原酸酯,在室温下完成烷基化。
