title: Novel and efficient synthesis of 4-dimethylamino-2-glycosylaminoquinazolines by cyclodesulfurization of glycosyl thioureas with dimethylcyanamide.
abstract: 4-dimethylamino-2-glycosylaminoquinazoline derivatives were synthesized by cyclodesulfurization of N-aryl-N'-glycosyl thioureas with dimethylcyanamide in the presence of silver triflate in good yields.
