Difuropyridines have been prepared from aldehydes and chitin‐derived 3‐acetamidofuran (3AF) under acid‐catalyzed conditions. Difuropyridines were comprehensively synthesized for the first time. The synthesized difuropyridines can be applied to prepare fluorescent probe analogs or catalyze decarboxylative reactions as photocatalysts.

从几丁质衍生的 3-乙酰氨基呋喃合成二呋喃吡啶及其在光催化反应中的应用


在酸催化条件下，由醛和几丁质衍生的 3-乙酰氨基呋喃 （3AF） 制备了二呋喃吡啶。首次全面合成了二呋喃吡啶类药物。合成的二呋喃吡啶可用于制备荧光探针类似物或作为光催化剂催化脱羧反应。
