  摘要：

  描述了新型非甾体类人孕激素受体（hPR）激动剂5-芳基-1,2-二氢-5H-chromeno [3,4-f]喹啉2的开发。将5-芳基基团引入1,2-二氢香豆素[3,4-f]喹啉核心1是促孕活动的关键。对5-芳基取代基的结构活性关系（SAR）研究产生了一系列有效的hPR激动剂，它们在细胞内显示出与天然激素孕酮（EC50 = 2.9 nM）类似的生物学活性（EC50 = 8-30 nM）。效率范围从28％到96％的检测。大多数类似物表现出与孕酮（Ki = 3.5 nM）相似或更高的结合亲和力（Ki = 0.41-3.6 nM）。三个代表性的类似物（13、15和24）在去卵巢大鼠的乳腺形态/子宫湿重测定中显示了体内活性。

  A series of benzo[c]chromen-6-ones are prepared by a Suzuki coupling and lactonization sequence starting with 2-methoxyphenylboronic acids and methyl 2-bromobenzoate derivatives. The use of ionic liquids in this synthesis has been explored. It was found that the Suzuki coupling proceeds much faster when a catalytic amount of the ionic liquid [BMIM][PF6] is used. By using the Lewis acidic ionic liquids
