title: Synthesis and vasorelaxant activity of 2-fluoromethylbenzopyran potassium channel openers.
abstract: The synthesis and vasorelaxant activity of 2-fluoromethylbenzopyran potassium channel openers are described. These (2-fluoromethyl) derivatives displayed smooth muscle relaxant activities comparable to or more potent than the corresponding 2-methyl analogues.
