Compounds having the formula
and pharmaceutically acceptable salts thereof wherein X is a single bond, O, CO, S, NH or N(lower alkyl); Y is O, S or NCN; and R¹ to R5' are as defined herein. These compounds have potassium channel activating activity and are useful, therefore for example, as cardiovascular agents.

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.
