Continuous flow has been used widely in process chemistry and academic settings for various applications. However, initial reaction discovery has generally remained "batch-exclusive" despite the existence of efficient, reproducible flow systems. We hereby disclose a workflow to bridge the gap between early medicinal chemistry efforts and process-scale development, showcased by the discovery and optimization
连续流已广泛用于过程化学和学术场合中的各种应用。然而,尽管存在有效的,可再现的流动系统,但最初的反应发现通常仍是“批料排斥的”。我们在此公开了一种工作流程,以弥合早期药物化学工作与工艺规模开发之间的差距,这是通过金属氯氧还蛋白催化的苄基氯化物与芳基溴化物之间的交叉偶联的发现和优化,然后由两个复杂的像化合物。
