Alkaline Hydrolysis and Alcoholysis of N-(Arylsulfonylamino)- and N-(N-Acetylarylsulfonylamino)succin- and -glutarimides
Alkaline hydrolysis and alcoholysis of N-(arylsulfonylamino)- and N-(N-acetylarylsulfonylamino)-succin- and glutarimides have been studied. The reaction outcome is determined both by the size of the imide ring and by the substituent on the imide nitrogen atom. Alkaline hydrolysis of N-(N-acetylarylsulfonylamino)-succin- and -glutarimides is characterized by different order of elimination of the acetyl group and opening of the imide ring. Heating of N-(arylsulfonylamino)glutarimides in methanol in the presence of sodium methoxide results in formation of methyl 5-(arylsulfonylhydrazino)-5-oxopentanoates, whereas the reaction with N-(arylsulfonylamino)succinimides stops at the stage of formation of the corresponding sodium salt.

CYCLODEHYDRATION OF N'-AROYL- AND N'-ARENESULFONYLHYDRAZIDES OF GLUTARIC ACID
The conditions for the cyclodehydration of the N'-aroyl- and N'-arenesulfonylhydrazides of glutaric acid were studied.It was established that the compounds do not form an imide when heated to the melting point during treatment with phosphorus pentoxide, a
