The one-pot four-component reaction of propargylated benzaldehydes, azide, dimedone, and urazoles in the presence of melamine trisulfonic acid, copper acetate, and sodium ascorbate was used for the synthesis of 1,2,3-triazolylmethoxyphenyl[1,2,4]triazoloindazole-1,3,8-trione derivatives as novel compounds.
