A transition-metal-free multi-functionalization reaction of β-trifluoromethyl enones and azacycles is first developed for the synthesis of valuable amino-2,3-dihydrofuran derivatives in moderate to good yields with excellent functional group tolerance. The multi-functionality transformation of carbonyl, alkenyl, and trifluoromethyl groups in β-trifluoromethyl enones streamlines the five-membered O-heterocycle assembly and facilitates the multiple-bond-forming cascade, thus providing a novel reaction mode for the defluorinative utilization of β-CF3-enones.

β-三氟亚甲基烯酮的多功能化使得2,3-二氢呋喃合成成为可能



首次开发了β-三氟亚甲基烯酮和氮杂环化合物的无过渡金属多功能化反应,用于合成有价值的氨基-2,3-二氢呋喃衍生物,收率中等至良好,具有优异的官能团耐受性。 β-三氟甲基烯酮中羰基、烯基和三氟甲基的多功能转化简化了五元O-杂环组装并促进了多重键形成级联,从而为β-三氟甲基烯酮的脱氟利用提供了一种新的反应模式。 CF 3 -烯酮。
