摘要

Abstract Three-component condensation of 3, 5-diamino-1, 2, 4-triazole with aromatic aldehydes and dimedone in dimethylformamide gives 2-amino-5-aryl-8, 8-dimethyl-5, 6, 7, 8, 9, 10-hexahydro [1, 2, 4] triazolo [3, 2-b] quinazolin-6-ones. The reaction of 3, 5-diamino- 1, 2, 4-triazole with dimedone in the absence of aldehyde involves dimethylformamide as one of the carbonyl components to afford 2-amino-8, 8-dimethyl-6, 7, 8, 9-tetrahydro [1, 2, ...
