Synthesis of new basic enol ethers with valuable pharmacological properties is described. The structure of these compounds is elucidated by 1H-and 13C-NMR-spectroscopy; the stereochemistry of the double bond is determined by use of the intramolecular nuclear Overhauser effect. An X-ray analysis of an isolated diastereomer confirms the proposed constitution.
