Abstract
- Microwave-promoted cyclocondensation of isoflavones with 3-amino[1,2,4]triazole gave 6-phenyl-7-(2-hydroxyphenyl)-1,2,4triazolo[4,3- a ]pyrimidines as intermediates. Subsequent photocyclization of these intermediates delivered dibenzo[ f , h ][1,2,4]triazolo[3,4- b ]quinazolines as final products. Water was the only by-product in this two-step procedure. The products showed distinct fluorescence properties both in solution and in the solid state .
