Abstract:
New 2,7-disubstituted 5-amino-6,8-dicyano-2,3-dihydro-3-oxo thiazolo[3,2-a]pyridines have been prepared. Their cyclization with formamide, nitrous acid and triethylorthoformate afforded a series of polycyclic heterocycles containing condensed pyrimidine and triazine rings. Antifungal tests were also performed.
