An efficient synthesis of tetrahydrotetrazolo[1,5-a]quinazoline derivatives by a three-component reaction of 5-aminotetrazole, arylaldehydes, and dimedoneĀ  %K tetrahydrotetrazolo[1,5-a]quinazoline %K p-TSA %K 5-aminotetrazole %K solvent-freeĀ  %R %X A series of tetrahydrotetrazolo[1,5-a]quinazoline derivatives were prepared by the three-component condensation reaction of 5-aminotetrazole (5-AT), benzaldehydes, and dimedone in the presence of p-toluenesulfonic acid (p-TSA) as a solid acid catalyst under solvent-free conditions. This protocol provides a simple one-step procedure with the advantages of easy work-up, mild reaction conditions and environmentally benign. %U https://scientiairanica.sharif.edu/article_3688_5afb86351834d283e868ee3edead0102.pdf
