Popis:	Furanone 3 and pyranone 4 were obtained by the reaction of o‐phenylene derivatives with tetronic acid 1 or pyrone 2, respectively. Under diazotization reaction, these two enaminone derivatives 3 and 4 cyclized rapidly with good yields to generate benzotriazoles 5. On the other hand, when enaminones 3 and 4 were allowed to react with carbondisulfide as electrophile, cyclization led to benzodiazepin‐2‐thiones 6 fused to dihydropyrone or tetronic acid moieties.
