the continuous flow synthesis of thieno[2,3-c]isoquinolin-5(4H)-one-A (TIQ-A), an important pharmacological tool and building block for PARP-1 inhibitors, has been developed. The synthesis involves a Suzuki coupling reaction to generate 3-phenylthiophene-2-carboxylic acid which is transformed into the corresponding acyl azide and readily cyclized by a thermal Curtius rearrangement. A statistical design
硫代[2,3 - c ]异喹啉-5(4 H)连续流动合成的高效多步方法)-one-A(TIQ-A)是一种重要的药理工具,是PARP-1抑制剂的基础。合成过程涉及Suzuki偶联反应,生成3-苯基噻吩-2-羧酸,将其转化为相应的酰基叠氮化物,并通过Curtius热重排使其容易环化。实验的统计设计(DoE)被用作进一步实验的决策制定的有价值的支持,从而能够开发出可靠且可靠的大规模制备方案。结果,反应容易,安全并且易于扩大规模。通过以克为单位进行反应,以高收率和高质量进行生物药理学评估,可以生产出所需的产品,从而测试了这种改进的流动方法的大规模适用性。
