Abstract
Iminoethers 1 react with phenylhydrazine to give naphtopyranes 2′ or with tosylhydrazine to yield the pyranopyrimidines 2. The condensation of these pyranopyrimidines with thionylchloride forms a new synthetic method for accessing to 1,2,3,5-thiatriazolopyrimidine-1-oxyde derivatives 3.Keywords
