A simple, efficient and practical procedure for the Biginelli reaction using strontium(II) triflate [Sr(OTf)2] as a novel catalyst is described undersolvent-freeconditions in high yields. The catalyst exhibited remarkable reactivity and it is reusable. Some of dihydropyrimidiones showed strong pesticidal activity.
