An unprecedented Pd‐catalyzed regioselective activation of gem‐difluorinated cyclopropanes induced by CC bond cleavage is reported. It provides a general and efficient access to a variety of 2‐fluoroallylic amines, ethers, esters, and alkylation products in high Z‐selectivity, which are important skeletons in many biologically active molecules. In addition, the transformation represents the first
据报道,空前的钯催化C inducedC键断裂诱导的宝石二氟化环丙烷的区域选择性活化。它提供了一种通用且有效的途径,可以高Z选择性地使用各种2-氟代烯丙基胺,醚,酯和烷基化产物,这些产物是许多生物活性分子的重要骨架。此外,该转变代表了在过渡金属催化的交叉偶联反应中作为反应伙伴的宝石二氟化环丙烷的首次普遍应用。
