ABSTRACT A thorough study on radical-induced cyclopropyl ring fragmentation with encompassed olefinic and cyclopropane environment has been performed. Interestingly, the fragmentation has occasioned onto a stereoselective synthesis of 3-allyl trans-2,3-dihydrobenzofurans with impressive yields. The trans-dihydrobenzofurans are present as central core in many molecules of medicinal interest and the
摘要 对包含烯烃和环丙烷环境的自由基诱导的环丙基环断裂进行了彻底的研究。有趣的是,片段化引发了立体选择性合成 3-烯丙基反式-2,3-二氢苯并呋喃,收率令人印象深刻。反式二氢苯并呋喃是许多具有药用价值的分子的中心核心,本协议提供了对嵌入式分子结构的直接访问。图形概要
