Estrogen sulfamates are promising hormones by oral administration. Therefore, generally applicable and convenient methods for the multigram synthesis of these derivatives are desirable. Numerous estra-1,3,5(10)-trienes derived from estrone, estradiol. 14 alpha,15 alpha-methylenestradiol, ethinylestradiol, and estriol have been esterified with
sulfamoyl chloride
and N-methylsulfamoyl chloride by a novel approach involving the use of 2,6-di-tert-butylpyridines as bases and chemoselective hydroxy group protections. These pathways circumvent the nonselective formation of esters and side reactions by in situ generated azasulfenes. For toxicological and clinical studies a new synthesis of estrone sulfamate on a 100-g scale was developed using dimethylformamide as the solvent and base.
