Troublesome alkoxythiophenes-mesomorphic behavior and highly efficient synthesis
The synthesis of a novel ferroelectric alkoxythiophene-containing liquid crystal is described together with the mesophase morphology of the material. The alkoxythiophene unit is introduced by a highly efficient ring closure of an appropriate gamma -ketoester using Lawesson's reagent as the sulfurating agent. Our new cyclization methodology represents the most efficient synthetic pathway for the synthesis of this unit.
