Physical Chemistry


Kinetics of nucleophilic substitution of halogen in diastereomeric dimethyl 4-bromo- and 4-iodoglutamates withortho-, meta-, andpara-substituted anilines was studied by HPLC. Thethreo-diastereomers of the halogenated derivatives react 3–5 times faster than theerythro ones. The structure of the transition state is discussed.
