synthetic routes of ELQ-300 and P4Q-391 including reliance on toxic heavy-metal reagents, harsh reaction conditions, and several low-yielding steps. Herein, we report the development of two alternative syntheses, which are reliable, high yielding, scalable, and have the potential to become a route of choice at process scale.
抗疟化合物 ELQ-300 和 P4Q-391 对疟原虫的血液和肝脏阶段非常有效,并且还具有有效的传播阻断活性。对体内功效、药代动力学和安全性的广泛评估需要这两种化合物的克量。ELQ-300 和 P4Q-391 的原始合成路线存在几个缺陷,包括依赖有毒重
金属试剂、反应条件苛刻和几个低产率步骤。在此,我们报告了两种替代合成的发展,它们可靠、高产、可扩展,并且有可能成为工艺规模的首选途径。
