Abstract

Syntheses were developed for 4‑aryl‑6‑ethoxy‑2-R‑furo[2,3‑b]pyridine‑5‑carbonitriles and ethyl esters of 5‑amino‑4‑aryl‑7‑methyl‑2-R‑1,9‑dioxa‑8‑azacyclopenta[b]naphthalene-6-carboxylic acids based on the reaction of 6‑amino‑4‑aryl‑2-R‑4H‑furo[2,3‑b]pyran‑5‑carbonitriles with ethyl acetoacetate and nucleophilic recyclization. The mechanisms of these reactions are considered.
