Discovery of 2-Arylbenzoxazoles as Upregulators of Utrophin Production for the Treatment of Duchenne Muscular Dystrophy
摘要:
A series of novel 2-arylbenzoxazoles that upregulate the production of utrophin in murine H2K cells, as assessed using a luciferase reporter linked assay, have been identified. This compound class appears to hold considerable promise as a potential treatment for Duchenne muscular dystrophy. Following the delineation of structure-activity relationships in the series, a number of potent upregulators were identified, and preliminary ADME evaluation is described. These studies have resulted in the identification of 1, a compound that has been progressed to clinical trials.

Recently, we have developed a method for catalytic regioselectivesynthesis of 2-substituted and 3-substituted benzofurans starting from phenols. The choice of reacting partner, olefin versus α,β-unsaturated acid, is critical to dictate the isomeric product formation. Instances are known where these olefinic partners did not complement each other and yield a similar outcome. In the current work, we
Triple CH functionalization: Palladium‐catalyzed synthesis of benzofurans and coumarins by reacting phenols and unactivated olefins is described. The reaction comprises sequential CH functionalization and shows diverse functional group compatibility. Preliminary mechanistic studies shed light into the possible mechanisms.

2-substituted benzo[b]furans in good yields throughpalladium-catalyzeddirect C–H bond functionalizations. It is important to note that the transformation of phenols with bromoalkynes into benzo[b]furans could be carried out in one pot with a simple and efficient tandem procedure.
苯并[ b ]呋喃在一个锅中根据苯酚与溴炔烃的加成/钯催化的CH键结合官能化制备。苯酚与溴代炔烃的加成反应以高收率生成了具有优异区域和立体选择性的(Z)-2-溴乙烯基苯基醚。所获得的(Z)-2-溴乙烯基苯基醚随后通过分子内环化进行处理,通过钯催化的直接C–H键官能化,以高收率获得了2-取代的苯并[ b ]呋喃。重要的是要注意,可以将溴代炔烃将苯酚转化为苯并[ b ]呋喃,可以通过简单而有效的串联程序在一个罐中进行。
