The results of our efforts aimed at the replacement of the benzopyran ring of the lead cardiac selective antiischemic ATP-sensitivepotassiumchannel (KATP) opener (4) are described. Systematic modification of the benzopyran ring of 4 resulted in the discovery of a structurally simpler acyclic analog (8) with slightly lower antiischemic potency than the lead compound 4.
