mild reaction conditions and with good functional‐group tolerance was developed. The development of the method was based on the invention of a stable, electrophilic, difluoromethylating reagent, difluoromethyl‐(4‐nitrophenyl)‐bis(carbomethoxy) methylide sulfonium ylide, which was synthesized by reaction of the easily available 4‐nitrophenyl (difluoromethyl)thioether and dimethyl diazomalonate in the

CDK8 plays a key role in acutemyeloidleukemia, colorectal cancer and other cancers. Here, a total of 54 compounds were designed and synthesized. Among them, the most potent one compound 43 (3-(1H-pyrrolo[2,3-b]pyridin-5-yl)benzamide), a novel CDK8 Ⅰ inhibitor, showed strong inhibitory activity against CDK8 (IC50 = 51.9 nM), good kinase selectivity, good anti AML cell proliferation activity (molm-13

While hydrogen bonding has been harnessed to bias siteselectivity in existing C(sp2)–H activation reactions, the potential for designing catalysts with hydrogen bond donors (HBDs) to enhance catalyst–substrate affinity and, thereby, facilitate otherwise unreactive C(sp3)–H activation remains to be demonstrated. Herein, we report the discovery of a ligand scaffold containing a remote amide motif that
