摘要

Reaction of ethyl azidoacetate with 6-formyl-4 chromanones, followed by cyclization of the azides obtained leads to 7, 8-dihydropyrano [2, 3-g] indol-9 (1 H)-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.
