In an ongoing effort to study the environmental fate of endocrine-active steroid hormones, we report the formation of phenolic rearrangement products (3 and 4) with a novel 6,5,8,5-ring system following aqueous photolysis of dienogest (1) and methyldienolone (2). The structures were established by analysis of 2D NMR and HRMS data, and that of 3 was confirmed by X-ray diffraction analysis. These photoproducts exhibit progestogenic and androgenic activity, albeit with less potency than their parent compounds.
为了研究具有内分泌活性的甾体激素在环境中的归宿,我们报告了在水中光解双羟孕酮(1)和甲羟孕素(2)后形成具有新型 6,5,8,5 环系的酚重排产物(3 和 4)。结构通过二维 NMR 和高分辨质谱数据分析得到确立,3 的结构通过 X 射线衍射分析得到确证。这些光产物表现出孕激素和雄激素活性,但效力低于其母体化合物。
