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.
本文介绍了氨基磺酸酯酰化和磺酰化的简便、高产程序。这些程序分别产生 N-酰基氨基磺酸酯和 N-磺酰基氨基磺酸酯官能团。 其中一种 N-酰基氨基磺酸酯的烷基化能力已得到证实。4- 氯苯基 N-乙酰乙酰基氨基磺酸酯是商用环状甜味剂安赛蜜 K 的直接前体,由 4- 氯苯基氨基磺酸酯和二乙烯制备而成。
