(1—3) were prepared by a modified Koenigs‐Knorr synthesis. As the alkaline hydrolysis of perpivaloylated methyl (2,3‐dichlorophenyl)‐ glucuronate 1a led to a dehydrated glucuronide, the preparation of peracetylated methyl dichlorophenylglucuronates with subsequent cleavage of the ester bindings under mild conditions was preferred.
