Abstract:
A Pd-catalyzed direct C–H trisallylation of azoles with alkyne has been described. A consecutive C(sp²)–H allylation/olefin isomerization/double C(sp³)–H allylation of azoles and alkyne via a palladium catalysis system proceeds efficiently to afford the corresponding C2-alkenylated azoles containing an all quaternary carbon center.
