Substituted thienopyrans and processes for preparing the thienopyrans are disclosed. The thienopyrans are useful as antihypertensive agents; antianginals are peripheral antivasoconstrictive agents.

The syntheses and spectral properties of novel dimethyl-substituted thieno-, - and pyranones are described.The uv spectra of the three systems are distinctly different as supported by HOMO/LUMO calculations. 5,6-Dihydro-5,5-dimethyl-7H-thienopyran-7-one (10) and 5,6-dihydro-6,6-dimethyl-4H-thienopyran-4-one (20) represent the first members of these thienopyranone ring systems.
