We have established the first catalytic C-C and C-N bond formation reactions of O-heterocycles (e.g., tetrahydrofuran, phthalane, and lactone derivatives) using iron trichloride as a catalyst in the presence of TMSN3 or allylsilanes accompanied by the ring opening of O-heterocycles. The reactions smoothly proceeded at room temperature to give the corresponding primary saturated alcohols from the 2-substituted tetrahydrofurans, ortho-substituted benzyl alcohols from phthalanes, and saturated carboxylic acids from lactones in high yields.
我们已经利用三氯化铁作为催化剂,在 TMSN3 或烯丙基硅烷的存在下,实现了 O-杂环(如四氢呋喃、邻苯二甲烷和内酯衍生物)的首例催化 C-C 和 C-N 键形成反应,同时伴随着 O-杂环的开环。这些反应在室温下顺利进行,从 2-取代的四氢呋喃中得到相应的仲饱和醇,从邻苯二甲烷中得到邻位取代的苄醇,从内酯中得到饱和羧酸,产率很高。
