Abstract

Liquid crystalline alkane-3, 4-dienoates (allenylacetates) have been synthesized. Most compounds incorporate a heterocyclic 1, 3, 4-thiadiazole ring or a pyrimidine ring as a constituent of the rigid core. These axial chiral allene derivatives were at first obtained as racemic mixtures. Some of them were also synthesized in enantiomerically enriched form by enantioselective synthesis. The compounds were investigated by polarizing microscopy ...
