Abstract
(R) and (S) enantiomers of the formula ##STR1## in which n is 1 or 2, W is as defined in the specification which are characterized in that X is halogen, SO.sub.3 H, SO.sub.2 Cl or SO.sub.2 NR.sub.1 R.sub.2 where R.sub.1 and R.sub.2 are, independently of one another, hydrogen, substituted or unsubstituted, branched or unbranched alkyl, substituted or unsubstituted aryl or heteroaryl, or R.sub.1 and R.sub.2 form, together with the nitrogen, a substituted or unsubstituted heterocycle, a process for their preparation and their use for racemate resolution.
Claims2
An (R) or (S) enantiomer of the formula ##STR11## in which n is 1 or 2 ,
- W is hydrogen, alkyl, cycloalkyl or the radical ##STR12## and, in the case where W is hydrogen, their anhydro compounds of the formula ##STR13## in which n is as defined above, which are characterized in that X is halogen, SO.sub.3 H, SO.sub.2 Cl or SO.sub.2 NR.sub.1 R.sub.2 where R.sub.1 and R.sub.2 are, independently of one another, hydrogen, substituted or unsubstituted, branched or unbranched alkyl, substituted or unsubstituted aryl or heteroaryl, or R.sub.1 and R.sub.2 form, together with the nitrogen, a substituted or unsubstituted heterocycle.
