Synthesis of certain heteroaryl-fused pyrimidines and pyridines and selena- and thia-diazoles with naphthyl substituent as potential antifungal agents.

A convenient route is reported for the synthesis of 1,2,3-selenadiazole, 1,2,3-thiadiazole, 1,2,4-triazolo[4,3-a]pyrimidine, tetrazolo[4,5-a]pyrimidine, benzimidazolo[1,2-a]pyrimidine and pyrazolo[3,4-b]pyridine derivatives in which the naphthyl nucleus is incorporated. The preliminary results of antifungal testing are reported.
