Reaction of ethyl azidoacetate with 6-formyl-4 chromanones, followed by cyclization of the azides obtained leads to 7,8-dihydropyranoindol-9 (1H)-one.One aspect of the chemical reactivity of these new tricyclic systems is described.The structure of the compounds isolated from various syntheses is established by proton nmr data.
