Synthesis of optically active γ-lactones and dopants for ferroelectric liquid crystals possessing a trifluoromethyl group
摘要:
A series of trans- and cis-gamma-lactones with high optical purity have been prepared from the lactonization of (S)-(-)-2-(trifluoromethyl)-4-pentenoic acid (>94% ee) under acidic conditions. These materials have been transformed into new types of dopant for ferroelectric liquid crystals possessing a trifluoromethyl group.
