A series of new, substituted 2,3-dihydropyran derivatives were synthesized by one-pot, three-component reactions of aldehydes, 1,3-dicarbonyl derivatives, and vinyl ethers catalyzed by ethylenediamine diacetate (EDDA) under solvent-free conditions. This new, simple, and efficient, solvent-free, one-pot approach to the substituted 2,3-dihydropyran scaffold starting from simple substrates was found to take place directly.
在无溶剂条件下,通过乙二胺二乙酸酯(EDDA)催化醛、1,3-二羰基衍生物和乙烯基醚的单锅三组分反应,合成了一系列新的取代型 2,3-二氢吡喃衍生物。这种新型、简单、高效、无溶剂、一锅式的方法可以直接从简单的底物开始生成取代的 2,3-二氢吡喃支架。
