Abstract

Sulphonate esters of formula - R1-CH2-CH2-CH(OSO2R3)-COOR2 (I) - are new: R1 = 5-6C cycloalkyl (opt. substd. by 1-7C alkyl) or opt. substd. phenyl; R2 = 1-7C alkyl; R3 = phenyl substd. by halo or NO2. The molecules are predominantly in the R or S configuration. - Pref. R1 = cyclohexyl or phenyl (opt. substd. by 1-4C alkyl or alkoxy); R2 = 1-4C alkyl; R3 = 4-nitrophenyl or 2,4-dinitrophenyl; the cpds. have predominantly the R configuration.
