The first enantioselective intramolecular C−H insertion and cyclopropanation reactions of donor‐ and donor/donor‐carbenes by a nondiazo approach are reported. The reactions were conducted in a one‐pot manner without slow addition and provided the desired dihydroindole, dihydrobenzofuran, tetrahydrofuran, and tetrahydropyrrole derivatives with up to 99 % ee and 100 % atom efficiency.
报道了通过非重氮方法进行的供体和供体/供体碳烯的首次对映选择性分子内CH插入和环丙烷化反应。反应以单锅方式进行,无需缓慢添加,并提供所需的二氢吲哚,二氢苯并呋喃,四氢呋喃和四氢吡咯衍生物,其ee最高可达99%,原子效率为100%。
