New cyclization reactions forming vinylcyclopropanes were developed wherein an alkenylrhodium(I) possessing a methoxy group at the allylic position as a potential leaving group acts as an allylic carbene equivalent. By this protocol, a vinylcyclopropane was installed in a complex cyclic structure in a single operation via successive multiple carbon-carbon bond formations.
开发了形成
乙烯基环丙烷的新环化反应,其中在烯丙基位置具有甲氧基作为潜在离去基团的烯基
铑 (I) 充当烯丙基卡宾等价物。通过该协议,
乙烯基环丙烷通过连续的多个碳-碳键形成在单个操作中安装在复杂的环状结构中。
