text: Efficient Cu(OTf)2-catalyzed synthesis of novel and diverse 2,3-dihydroquinazolin-4(1H)-ones.
  An efficient one-pot synthesis of various 2,3-dihydroquinazolin-4(1H)-one derivatives was accomplished using Cu(OTf)2-catalyzed multi-component reactions between isatoic anhydride, ketones, and amines. The method has several significant advantages; mild reaction conditions, easy handling, and efficiency of catalyst.
