aromatic and heteroaromatic aldehydes, imidazo[4, 5-e][1, 3]thiazolo[3, 2-b][1, 2, 4]triazine-2, 7-diones, perhydroimidazo[4, 4]triazine-3-thione, aldol-crotonic condensation, one-pot condensationAbstract
Previously unknown (Z)-6-aryl(hetaryl)methylidene derivatives of imidazo[4,5-e][1,3]thiazolo[3,2-b][1,2,4]triazine-2,7-diones were synthesized by aldol-crotonic condensation of imidazo[4,5-e][1,3]thiazolo[3,2-b][1,2,4]triazine-2,7-diones with aromatic or heteroaromatic aldehydes, or by three-component condensation of imidazo[4,5-e][1,2,4]triazine-3-thione, bromoacetic acid, and aldehyde.
