Substituted pyrans and furans are core structures found in a wide variety of natural products and biologically active compounds. Herein, we report a practical and mild catalytic method for the synthesis of substituted pyrans and furans using molecular iodine, a simple and inexpensive catalyst. The method described is performed under solvent-free conditions at an ambient temperature and atmosphere,
取代的吡喃和呋喃是广泛存在于各种天然产物和生物活性化合物中的核心结构。在此,我们报告了一种使用分子碘(一种简单且廉价的催化剂)合成取代吡喃和呋喃的实用且温和的催化方法。所描述的方法是在环境温度和气氛下在无溶剂条件下进行的,因此为当前可用的反应方案提供了一种简便实用的替代方案。实验研究和密度泛函理论计算的结合揭示了对这种看似简单的反应的有趣的机械见解。
