Abstract
Optically active compounds of the formula I ##STR1## where R is C.sub.1 -C.sub.12 -alkyl or -perfluoroalkyl in which one or two non-adjacent CH.sub.2 or CF.sub.2 groups can also be replaced by --O-- and/or --CO-- and/or --CO--O-- and/or --CH.dbd.CH-- and/or --CH-halogen- and/or --CHCN-- and/or --O--CO--CH-halogen- and/or --O--CO--CHCN--, or is C.sub.1 -C.sub.12 -alkyl which can have a terminal chemically reactive group and in which a CH.sub.2 group can be replaced by --O--, PA1 A.sup.1 and A.sup.2 are each, independently of one another, 1,4-phenylene which is unsubstituted or substituted by one or two F and/or Cl and/or Br atoms and/or CH.sub.3 groups and/or CN groups and in which one or two CH groups can also be replaced by N, 1,4-cyclohexylene in which one or two non-adjacent CH.sub.2 groups can also be replaced by --O-- and/or --S--, 1,4-piperidinediyl, 1,4-bicyclo[2.2.2]octylene, 2,6-naphthalenediyl, decahydro-2,6-naphthalenediyl or 1,2,3,4-tetrahydro-2,6-naphthalenediyl, PA1 A.sup.3 is unsubstituted or substituted phenyl, PA1 Z is --CO--O--, --O--CO--, --CH.sub.2 CH.sub.2 --, --OCH.sub.2 --, --CH.sub.2 O--, --C.tbd.C-- or a single bond and PA1 m is 0, 1, 2 or 3.
