Aliphatic Liquid Crystals, 5 - The Influence of Angular 4a- and 8a-Methyl Groups on the Nematic Character of all-trans-Perhydro-2-phenanthrenol Esters

The synthesis of the 4a- and 8a-methyl-7-hexylperhydro-2-phenanthrenol esters 2b - d and 3b - d is described.Compared to their methyl free counterparts 1b - d they posses lower clearing points and therefore narrower nematic ranges.The 8a-methyl derivatives are also prepared in the optically active form.
