Optical resolution of 5-alkyl-δ-valerolactones and synthesis of optically active 5-fluoroalkanols

Optical resolutions of 5-alkyl-δ-valerolactones were carried out by derivatization to the diastereomeric amides, in which (R)-(+)-1-(1-naphthyl)ethylamine or (S)-(-)-1-phenylethylamine were used as resolving agents. Optically active 5-fluoroalkanols, useful intermediates for fluorinated ferroelectric liquid crystals, were derived from the resolved lactones in four steps without racemization.

Synthesis and properties of ferroelectric liquid crystals derived from 5-alkyl-δ-valerolactones

New homologous FLCs (I-II-n [n=1-4]) derived from optically active 5-alkyl-6-valerolactones were synthesized. Their mesomorphic properties were systematically investigated with respect to their molecular structures, which were different in terms of the le
