Convenient, high-yield procedures for the acylation and sulfonylation of sulfamate esters are described. These procedures yield the N-acylsulfamate ester and the N-sulfonylsulfamate ester functionalities, respectively. The alkylating ability of one of the N-acylated sulfamate esters prepared has been demonstrated. 4-Chlorophenyl N-acetoacetylsulfamate, an immediate precursor to the commercial cyclic sweetener Acesulfam K, has been prepared from 4-chlorophenyl sulfamate and diketene.
