New liquid-crystal compounds, (+)-4-alkoxyphenyl 4-[5-(2-methylbutyl)-1,3-oxathian-2-yl]-benzoates (<B>9</B>), have been synthesized. The mesomorphic behaviors of these compounds were compared with those of (+)-4-(2-methylbutoxy)phenyl 4-(5-alkyl-1,3-oxathian-2-yl)-benzoates and (+)-4-(5-alkyl-1,3-oxathian–2-yl)phenyl-4-(2-methylbutoxy)benzoates; compounds <B>9</B> exhibit a cholesteric phase and their transtition temperatures to isotropic were found to be lower those of the corresponding compounds. These properties seem to originate in the wider molecular width caused by both the 2-methylbutyl group at the 5 position of the 1,3-oxathiane ring and the molecular bend in the 1,3-oxathiane ring.
