Abstract

Optically pure enantiomers of cis-2,2-dimethyl-3-(2,2 dihalo-vinyl) -cyclopropane carboxylic acid cpds. (I) are prepd. by the resolution of these with optically active 2-benzyl-amino butanol The diastereisomeric forms of acids (I) are sepd. by a single antipode of 2-benzyl-amino -butanol, followed by the isolation of the optically pure cpds. of (I).
