A convenient synthesis of benzothiophene derivatives
(Methylthio)- and 2-bromo-1-(methylthio)benzene are useful synthons to prepare monometallated and bimetallated intermediates which lead to 1-benzothiophenes functionalized in the three and/or two positions.

Synthesis and structure of new basic enol ethers
Synthesis of new basic enol ethers with valuable pharmacological properties is described. The structure of these compounds is elucidated by the 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.
