A facile one-pot synthesis of functionalized azido chromenes was achieved by Michael addition of alpha-azido ketones on iminocoumarin derivatives obtained from salicylaldehydes and malononitrile. Synthesized azido chromenes were successfully transformed into triazolyl chromenes by the [3+2] cycloaddition reaction. (C) 2011 Elsevier Ltd. All rights reserved.
