reactivity of “furan-ynes” in combination with pyridine and quinoline N-oxides in the presence of a Au(I) catalyst, has been studied, enabling the synthesis of three different heterocyclic scaffolds. Selective access to two out of the three possible products, a dihydropyridinone and a furan enone, has been achieved through the fine-tuning of the reaction conditions. The reactions proceed smoothly at room
已经研究了“呋喃-炔”与吡啶和喹啉N-氧化物在 Au(I) 催化剂存在下的反应性,从而能够合成三种不同的杂环支架。通过微调反应条件,可以选择性地获得三种可能的产物中的两种,即二氢吡啶酮和呋喃烯酮。该反应在室温和露天条件下顺利进行,并进一步扩展到广泛的底物范围,从而得到功能化的二氢吡啶酮和吡喃酮。
