Liquid crystalline substituted dihydrobenzene derivatives
-
, (2008/06/13)
Particular 1,4-substituted dihydrobenzene derivatives are useful as liquid crystalline materials. They are represented by the following formula (I): wherein A means a 1,4-dihydrophenylene group, R denotes a hydrogen atom or an alkyl or trans-4-alkylcyclohexyl group, R' represents a hydrogen or halogen atom, a trifluoromethyl, trifluoromethoxy, cyano, alkyl, alkoxyl or carboxyl group or a group -COO-B-R'' in which B stands for an unsubstituted or halogen-substituted 1,4-phenylene or 1,4-cyclohexenylene group and R'' represents a halogen atom or a cyano, alkyl or alkoxyl group, and X, Y and Z individually mean a hydrogen or halogen atom.

Claisen rearrangement of the acrylic esters 7 and 21 transfers the configuration of the cyclohexenols trans-2 and trans-17 to the aldehydes 11 and 23.Robinson annelation converts the latter to the title compounds 15a and 27a.The synthetic sequence is desi
