enables the expeditious synthesis of oxazolines from amides via Pd-catalyzed C(sp3)–H functionalization has been described. Preliminary studies indicate that the reaction might go through a chlorination/nucleophilic cyclization sequence, and the high efficiency of this sequence is enhanced by the in situ cyclative capture of the chlorinated intermediate. The resulting oxazolines can be further converted
