3,15-substituted estrone compounds which act as inhibitors of 17β-hydroxysteroid dehydrogenase type I (17β-HSD1), salts thereof, pharmaceutical preparations containing such compounds, processes for preparing such compounds, and therapeutic uses of such compounds, particularly in the treatment or inhibition of steroid hormone dependent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of 17β-hydroxysteroid dehydrogenase type I enzymes and/or requiring the lowering of the endogenous 17β-estradiol concentration, as well as the general use of selective 17β-hydroxysteroid dehydrogenase type 1 inhibitors which possess in addition no or only pure antagonistic binding affinities to the estrogen receptor for the treatment or inhibition of benign gynecological disorders, particularly endometriosis.

inhibition of human steroidsulfatase (STS). Among the carbamate (6), thiocarbamate (8), cyanate (7), formate (9), and acetate (10) analogs of estrone, only 9 was found to inhibit STS in a time- and concentration-dependent manner. With an IC(50) of 0.42 microM 9 is the first potent inactivator of STS which does not feature the sulfamate group. Furthermore a formate-type inhibitor featuring a benzoxazole

A convenient method to prepare aryl formates is reported herein that exploits difluorocarbene to serve as a CO surrogate. This reaction is proposed to occur through a sequential O-difluoromethylation of phenol, followed by α-C–F bond functionalization of the resulting aryl difluoromethyl ether intermediate by phenol or moisture through fluorosemiacetal or orthoformate intermediates. Late-stage modification
本文报道了一种制备甲酸芳酯的便捷方法,该方法利用二氟卡宾作为 CO 替代物。该反应被认为是通过苯酚的顺序O-二氟甲基化,然后通过苯酚或水分通过氟半缩醛或原甲酸酯中间体对所得芳基二氟甲基醚中间体进行 α-C-F 键官能化而发生的。证明了生物和材料活性化合物的后期修饰。
