A P(NMe2)3-mediated reductive intramolecular cyclopropanation is developed for the first time, which provides facile access to a wide variety of cyclopropane-fused heterocycles including chromanes, tetrahydroquinolines, lactones, and lactams. Catalytic hydrogenative ring-expansion of the cyclopropane-fused heterocycles is also elaborated, leading to various structurally important medium-sized heterocycles
首次开发了AP(NMe 2)3介导的还原性分子内环丙烷化反应,该反应可轻松利用各种环丙烷稠合的杂环,包括苯并二氢吡喃,四氢喹啉,内酯和内酰胺。还详细说明了环丙烷稠合杂环的催化加氢扩环,从而产生了各种结构上重要的中等尺寸的杂环。
