摘要：

An efficient epoxidation of chalcones with urea-hydrogen peroxide (UHP) under ultrasound irradiation was carried out in 78-93% yields. Compared with the classical method, the advantages of protocol are to use a safer oxidant, mild conditions, no toxic solvent and shorter reaction time. (c) 2008 Elsevier B.V. All rights reserved.
