外文摘要：The new reactions between o-hydroxyphenyl enaminones and Langlois reagent(CF3SO2Na)for the tun-able synthesis of 3-(trifluoromethylthio)chromones and 3-trifluoromethylsulfinyl chromones are reported herein.Both type of reactions proceed under transition metal-free conditions.In addition,the conditions for the synthesis of 3-trifluoromethylsulfinyl chromones have also been found to be applicable for the synthesis of 3-alkyl/arylsulfinyl chromones.
