Facile Condensation of 2‐Aminobenzaldehydes into Azolo[4,5‐b]Quinolones

Abstract

An operationally simple approach to azolo[4,5‐b]quinolines based on the condensation of 2‐aminobenzaldehydes with various azolones is developed. A series of 22 compounds was synthesized typically in good yields (40–92 %).
