The optimization and synthesis of biaryl PDE4D allosteric modulator D159687 was achieved on gram scale via a concise two-step process. The synthesis features sequential chemoselective Suzuki coupling reactions taking advantage of different reactivity profiles of benzyl versus aryl halides. The method was then applied to the synthesis of two additional PDE4D allosteric modulators, D159404 and D159153
联芳基PDE4D变构调节剂D159687的优化和合成是通过简洁的两步过程以克为单位实现的。合成具有顺序化学选择性的Suzuki偶联反应,利用了苄基卤化物与芳基卤化物的不同反应活性。然后将该方法应用于两种其他PDE4D变构调节剂D159404和D159153的合成。这些PDE4变构调节剂的有效合成将允许对这些化合物进行进一步的生物学评估,开发的方法将通过组合化学方法快速形成类似物。
