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。
