Iodine-Catalyzed Versatile Synthesis of 4,6-Diarylpyrimidin-2(1H)-ones (DAPMs) via One-Pot, Multicomponent Reaction

Abstract

An efficient, solvent-free, one-pot, three-component cyclocondensation reaction between aldehyde, ketone, and urea to give 4,6-diarylpyrimidin-2(1H)-ones (DAPMs) using iodine as catalyst is described. This new protocol provides a simple and environmentally benign route along with the associated advantages of good to excellent yield of the products (90–96%) and short reaction times (5–15 min) at 80 °C.
