钯催化的Suzuki反应是在4-氯噻吩并[2,3- d ]嘧啶上在经典加热条件下和在微波辐射下进行的。在此研究中,由于根据所用条件分离出两种化合物,因此获得了一些出乎意料的结果。对实验细节的仔细研究表明,当使用脱气溶剂时(在传统加热和微波加热中)都发生了预期的C C键形成,而在使用前未用氩气对溶剂脱气时发生了意外的C O键形成。J.杂环化学。,46,459(2009)。
Palladium-catalyzed Suzuki reactions were performed on 4-chlorothieno[2,3-d]pyrimidines under classical heating conditions and under microwave irradiation. Some unexpected results were obtained during this study as two kinds of compounds were isolated depending on the conditions used. A careful investigation of experimental details has shown that the expected CC bondformation occurred when degassed

Discovery of Pyrrolo[2,3-d]pyrimidine derivatives as potent and selective colony stimulating factor 1 receptor kinase inhibitors
Colony stimulating factor 1receptor kinase (CSF1R) plays an integral role in tumor-associated macrophage repolarization and has emerged as a novel therapeutic target for cancer immunotherapy. Most of the current CSF1R kinase inhibitors lack selectivity between CSF1R kinase and other type III growth factor receptor members. Herein, we report a potent and selective CSF1R inhibitor 18h, which displays an
