Popis:	The novel benzoxathiinopyridines (4) and (5), the hitherto unknown di- benzopyrone (6) and the heterocyclic enaminone (7) have been synthesi- zed by ring transformations of phenyl 7-fluoro-4-chromone-3-sulfonate (1) with methyl 3-oxopentanoate (2) in the presence of ammonium acetate (3). The structures of (4-7) were determinated by spectroscopic methods and the reaction pathways of formation for these compounds are discussed
