A straightforward and convenient route has been developed for the synthesis of 3‐unsubstituted phthalide derivatives from aryl amides and paraformaldehyde by ruthenium(II)‐catalyzed C–H activation. The reaction proceeds through tandem ortho‐hydroxymethylation of aryl amide and subsequent intramolecular lactonization.
已经开发出了一种简单易行的途径,可以通过钌(II)催化的CH活化从芳基酰胺和多聚甲醛合成3-未取代的邻苯二甲酸酯衍生物。该反应通过芳基酰胺的串联邻羟基甲基化和随后的分子内内酯化而进行。
