An effective synthesis of dibenzo[4-(heteroaryl)pyrido]aza-14-crown-4 ethers was elaborated by one-step domino condensation of 1,4-bis(2-acetylphenoxy)-3-oxapentane, thiophene- and pyrrolcarbaldehyde and ammonia, in acetic acid. Molecular structure of dibenzo[4-(2-thienyl)pyrido]aza-14-crown-4 ether was established by X-ray analysis. © ISUCT Publishing.
