SYNTHESIS OF NEW OPTICALLY ACTIVE CYANOCYCLOPROPANES AS CHIRAL DOPANTS FOR FERROELECTRIC LIQUID CRYSTALS

Kusumoto, Tetsuo,Nakayama, Akiko,Sato, Ken-ichi,Hiyama, Tamejiro,Takehara, Sadao,et al.

, p. 939 - 942 (2007/10/02)

Optically active 2-alkyl-1-aryl-cyanocyclopropanes were synthesized from 2-aryl-4-hydroxyalkanenitriles which in turn were obtained by the reaction of chiral 1,2-epoxyalkanes with the carbanions derived from arylacetonitriles.
