Free-radical mediated cyclopropane ring opening of 2-silylbicyclo[3.1.0]hexane 1 has been carried out leading to the corresponding trisubstituted cyclopentenes 5 and 6 in good yield with complete 1,2-stereocontrol. [3+2]-Annulation has also been performed by trapping the resulting radical with electron-rich and electron-poor olefins, leading to the corresponding polycyclic compounds. Further studies
已经进行了自由基介导的2-甲硅烷基双环[3.1.0]己烷1的环丙烷开环反应,从而以良好的收率得到了相应的三取代的环戊烯5和6,并实现了完全的1,2-立体控制。[3 + 2]-环化反应还通过用富电子和贫电子的烯烃捕获生成的自由基来进行,从而生成相应的多环化合物。还描述了使用这种方法对二氢吡啶和吡咯进行官能化的进一步研究。
