A new strategy for the construction of a CCâCF3 subunit has been developed via CuBr-catalyzed domino cyclizationâtrifluoromethylation of homopropargyl amines with Umemoto's reagent. 4-Trifluoromethyl-2,3-dihydro-pyrroliums were produced in high yields. The usefulness of these products has been demonstrated by the transformation of them into various other trifluoromethylated molecules.
一种新的CC–
CF3亚单位构建策略已被开发,方法是通过CuBr催化的多重环化–三
氟甲基化反应,将同苄炔胺与Umemoto试剂反应。得到了高产率的4-三
氟甲基-2,3-二氢
吡咯里离子。这些产物的实用性通过将其转化为各种其他三
氟甲基化分子得到了证明。
