Four-component tandem procedure to prepare a series of dihydrotetrazolopyrimidinyl carbamides starting from diketene, amine, 5-aminotetrazole, and aldehyde was newly developed in the presence of iodine. Most of the products were obtained in moderate to good yield after simple workup of the final reaction mixture, the scope and limitation was also probed into..
