Bistributylstannyl-2(5H)-furanone 4a has been prepared from 3-(tetrahydropyran-2-yl)oxy but-2-ynoate and shown to exhibit good selectivity in its Stille reactions with a range of halogenated compounds, leading to 4-substituted-3-stannyl-2(5H)-furanones, in generally moderate yield. Under certain reaction conditions, doubly substituted products were also isolated from the reactions. The 3,4-bistrimethylstannyl
双三丁基锡烷基-2(5 H)-呋喃酮4a是由3-(四氢吡喃-2-基)氧基丁-2-丙酮酸酯制得的,并显示出在其Stille反应中与一系列卤代化合物具有良好的选择性,从而导致4-取代的3-stannyl-2(5 H)-呋喃酮,通常收率中等。在某些反应条件下,还从反应中分离出双取代的产物。制备了对应于4a的3,4-双三甲基锡烷基呋喃酮4b,但是在对其进行Stille反应的所有尝试中都将其分解。
