Abstract
Abstract The title compounds were prepared by short enantioselective syntheses from 7- geranytoxycoumarin. The key step to induce optical activity was a SHARPLESS epoxidation. Conditions of electrophilic cyclization were found to obtain good yields. This approach allowed also to obtain the glycol (+)-marmin.
