A potassium‐bis(trimethylsilyl)amide‐mediated cyclopropanation of allyl phosphates with silylboronates has been developed. Unlike the reported copper‐catalyzed allylic substitution reactions, the nucleophile selectively attacks at the β‐position of the allylic substrates under the present reaction conditions. The mechanism of this process has also been investigated, thus indicating the involvement
已经开发了一种由钾(双(三甲基甲硅烷基)酰胺介导的烯丙基磷酸酯与甲硅烷基硼酸酯的环丙烷化反应)。与报道的铜催化的烯丙基取代反应不同,亲核试剂在当前反应条件下选择性攻击烯丙基底物的β位置。还已经研究了该过程的机理,从而表明甲硅烷基钾物质作为活性亲核组分的参与。
