describe a new, iron-catalyzed method for cyclopropanation of a sterically and electronically diverse range of unactivated alkenes. The strategy enables synthesis of novel classes of cyclopropanes bearing alkyl, benzyl, allyl, halide, and heteroatom substituents, as well as spirocyclic and fused bicycles. By harnessing non-stabilized alkyl carbenes, novel substituted cyclopropanes can now be accessed to facilitate
DeMuynck 及其同事描述了一种新的铁催化方法,用于对一系列空间和电子不同的未活化烯烃进行环丙烷化。该策略能够合成带有烷基、苄基、烯丙基、卤化物和杂原子取代基的新型环丙烷,以及螺环和稠合双环。通过利用不稳定的烷基卡宾,现在可以获得新型取代环丙烷,以促进含有这些特殊基序的新药物的发现。为这种不稳定的烷基卡宾反应性提供了机理见解。
