Abstract

Enantiomerically pure N-(3,5-dichlorophenyl)-2-hydroxysuccinimides (NDHS) and N-(3,5-dichlorophenyl)-2-hy­droxysuccinimide-O-sulfates (NSC) have been synthesized in our laboratory in order to address their selectively related nephrotoxic mechanism. The key step for NDHS synthesis is the intramolecular nucleophilic cyclization via the amide N-atom with retention of configuration of the original stereogenic center. The corresponding sulfate conjugates (R)-NSC and (S)-NSC were prepared by reaction of enantiomeric NDHS with chlorosulfonic acid at -78 °C.
