A phenyliodine(III) diacetate (PIDA)/CuBr-mediated construction of the novel 3H,3'H-spiro[benzofuran-2,2'-benzo[b]thiophene]-3,3'-dione skeleton was realized from the reaction of (Z)-3-hydroxy-1-(2-hydroxyphenyl)-3-(2-halogenphenyl)prop-2-en-1-ones with p

Methods were developed for the synthesis of 1-aryl-9H-thieno[3,4-b]chromon- 9-ones based on the reaction of bromo and dibromo derivatives of 2-methyl-4H-chromon-4-one with thioacetamide in DMF. The thienochromones were modified and their fluorescence prop
