Reaction of 1,3,4-Thiadiazolo and 1,3,4-Triazoloquinazoline Derivatives With Active Methylene Compounds

Fused quinazoline derivatives 1 and 4 react with active methylene compounds and depending on the annelated five-membered ring, two types of transformations have been observed.The 1,3,4-thiadiazoloquinazoline 1, underwent the five-membered ring open
