  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 properties were studied. Bis(thienochromones) were synthesized by the reaction of thienochromones with ketoaldehydes.

  根据 2-甲基-4H-色-4-酮的溴和二溴衍生物与硫代乙酰胺在 DMF 中的反应，开发了合成 1-芳基-9H-噻吩并[3,4-b]色-9-酮的方法。对这些噻吩一氢色酮进行了修饰，并研究了它们的荧光特性。双（噻吩一氢色酮）是通过噻吩一氢色酮与酮醛反应合成的。

  A novel and convenient method for the synthesis of a wide range of polyfunctional imidazole derivatives based on the three-component condensation of imidazole N-oxides with CH-acids and arylglyoxals has been developed. This reaction proceeds smoothly in moderate-to-good yields with a wide range of starting materials.

  It was found that the condensation of two equivalents of 4-hydroxy-6-methyl-2H-pyran-2-one or 4-hydroxycoumarin with arylglyoxals in boiling formic acid leads to 4H-furo[3,2-c]-pyran-4-ones or 4H-furo[3,2-c]chromen-4-ones, respectively.
