Claim:
A compound of formula I in which R* 1 is a chiral radical, Z 1 is, if present more than once, in each case, independently of one another, —CH 2 —CH 2 —, —CH═CH—, —C≡C—, —COO—, —OCO—, —CH 2 O—, —OCH 2 —, —CF 2 O—, —OCF 2 —, —(CH 2 ) 4 —, —CF═CF—, —CH═CF—, —CF═CH—, —CH 2 —, —CF 2 —, —CHF—, —O—, —S— or a single bond, is, if present more than once, in each case, independently of one another, (a) a trans-1,4-cyclohexylene radical, in which one or more non-adjacent CH 2 groups are optionally replaced by —O— and/or —S—, (b) a 1,4-cyclohexenylene radical, (c) a 1,4-phenylene radical, in which one or two CH groups are optionally replaced by N, or (d) 1,4-bicyclo[2.2.2]octylene, piperidine-1,4-diyl, naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl, or 1,2,3,4-tetrahydronaphthalene-2,6-diyl, where these radicals (a) to (d) and the phenolic benzene ring is optionally mono- or polysubstituted by F atoms, and n 1 is 1, 2 or 3, wherein A) R* 1 is a chiral radical of the following formula in which K is a single bond, alkylene having 1 to 9 C atoms, alkenylene or alkynylene having 2 to 9 C atoms, wherein one, two or more of the —CH 2 — groups present in the alkylene, alkenylene or alkynylene are optionally replaced by —O—, —C═O— or —S—, but where no two O atoms are bonded directly to one another, and the alkylene, alkenylene or alkynylene are optionally substituted by halogen, or R* 1 is Q is H or halogen, n and m are different from one another and, independently of one another, are 1 to 11, p is 0 or 1, and L, M and N, each, independently of one another, but differently from one another and from are hydrogen, halogen, aryl or cycloalkyl, alkyl or alkoxy having 1 to 11 C atoms, alkenyl, alkenyloxy, alkynyl or alkynyloxy having 2 to 11 C atoms, where one, two or more of the —CH 2 — groups present in the alkyl, alkoxy, alkenyl, alkenyloxy, alkynyl or alkynyloxy are optionally replaced by —O—, —C═O— or —S—, but where no two O atoms are bonded directly to one another and the alkyl, alkoxy, alkenyl, alkenyloxy, alkynyl or alkynyloxy are optionally substituted by halogen; or B) R* 1 is a chiral radical of one of the following formulae in which Q is H or halogen, n and m are different from one another and, independently of one another, are 1 to 11, p is 0 or 1, and r is 0 to 4.
