A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of drug
描述了在温和条件下一系列杂芳基氯化物,溴化物和碘化物的钯催化的二氟甲基化。各种杂芳基卤化物(例如吡啶基,嘧啶基,吡唑基,呋喃基,噻吩基,吡唑基,咪唑基,噻唑基和恶唑基卤化物)被有效地二氟甲基化,因此为药物化学家提供了制备具有二氟甲基化杂芳基单元的候选药物的替代选择。
