  New fluorogenic substrate for the first continuous steroid sulfatase assay

  摘要：

  The screening for new inhibitors of steroid sulfatase requires an efficient test system. To overcome the shortcomings of the available discontinuous fluorimetric assay, several coumarin-type compounds were investigated as potential new substrates. 3,4-Benzocoumarin 7-O-sulfate was found to have appropriate substrate properties for the establishment of the first direct continuous assay of steroid sulfatase.

  有氧铁基交叉脱氢偶联能够有效地以多样性为导向合成基于香豆素的选择性雌激素受体调节剂

  摘要：

  将铁基交叉脱氢偶联（CDC）方法应用于香豆雌酚基选择性雌激素受体调节剂（SERM）的多样性合成，代表了CDC化学在天然产物合成中的首次应用。香豆雌酚两步合成的第一阶段涉及 2-(2,4-二甲氧基苯甲酰基)乙酸乙酯和 3-甲氧基苯酚之间的改良有氧氧化交叉偶联，以及 FeCl 3(10 mol%) 作为催化剂。然后对苯并呋喃偶联产物进行连续的脱保护和内酯化步骤，得到总产率为 59% 的天然产物。基于这种新方法制备了其他香豆雌酚类似物，并测试了它们对雌激素受体 (ER) 依赖性 MCF-7 和非 ER 依赖性 MDA-MB-231 乳腺癌细胞增殖的影响。结果，发现了具有乙酰胺基团而不是香豆雌酚的 9-羟基基团的新型雌激素受体配体。既9- acetamidocoumestrol和8 acetamidocoumestrol被发现比对雌激素依赖性MCF-7乳腺癌细胞的天然产物更多活跃，IC 50个的30和9个N值中号分别。

• Copper-mediated synthesis of coumestans via C(sp 2 )-H functionalization: Protective group free route to coumestrol and 4′- O -methylcoumestrol

  日期：2017.9

  A simple and efficient two step synthesis of coumestans is described. The key reaction in the synthesis is the use of easily available Cu(OAc)2 for CH functionalization of 3-(2-hydroxyphenyl)coumarin to give coumestan ring system via formal oxidative cyclization. This approach provided a short protective group free route to naturally occurring coumestrol and 4′-O-methylcoumestrol.

  描述了一种简单高效的香豆素两步合成法。合成中的关键反应是使用易得的Cu（OAc）2将3-（2-羟苯基）香豆素进行C H官能化，以通过正式的氧化环化反应生成Coumestan环系统。该方法为天然存在的香豆雌酚和4'- O-甲基香豆雌酚提供了一条简短的无保护基团的途径。

  A copper-catalyzed intramolecular cross dehydrogenative C–O coupling reaction of 2′-hydroxyl-3-arylcoumarins was developed. This protocol provided a facile and efficient strategy for the construction of natural coumestans and derivatives in moderate to high yields. This transformation exhibited good functional group compatibility and was amenable to substrates with free phenolic hydroxyl groups.
