Abstract

An ultrasound-promoted three-component reaction provides C3-cyanomethylated imidazo[1,2-a]pyridines under catalyst-free, oxidant-free, and mild conditions. A series of C3-cyanomethylated imidazo[1,2-a]pyridines were rapidly prepared with satisfactory yields and good functional group compatibility.
