A new strategy is described to synthesize 19-norsteroids with substituents at C-6, C-11 and C-17. The strategy is applied to the synthesis of 11β-[4-(dimethylamino)phenyl]-6β-methyl-4′, 5′– -dihydrospiro[estra-4,9-diene-17,2′-(3′H)-furan]-3-one (15, Org 31710) and some related compounds. These compounds have been shown to have potent antiprogestational activity and, compared to previously described
描述了一种新的策略,以合成在C-6,C-11和C-17处带有取代基的19-降糖甾体。该策略适用于11β-[4-(二甲基氨基)苯基]-6β-甲基-4',5'-二氢螺[estra-4,9-二烯-17,2'-(3'H)的合成-呋喃] -3-one(15,Org 31710)和一些相关化合物。已显示这些化合物具有有效的抗孕活性,并且与先前描述的11-芳基-19-降糖甾体相比,对糖皮质激素受体的亲和力大大降低。
