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
口服硫酸雌激素是有希望的激素。因此,期望用于这些衍生物的多谱图合成的普遍适用且方便的方法。衍生自雌酮,雌二醇的大量estra-1,3,5(10)-三烯。已通过一种新颖的方法将氨磺酰氯和N-甲基氨磺酰氯与14α,15α-亚甲基雌二醇,乙炔雌二醇和雌三醇酯化,该新颖方法涉及使用2,6-二叔丁基吡啶作为碱和化学选择性羟基保护基。这些途径通过原位产生的氮杂亚砜来避免酯的非选择性形成和副反应。为了进行毒理学和临床研究,使用二甲基甲酰胺作为溶剂和碱,开发了一种100 g规模的氨基磺酸雌酮的新合成方法。
