The expansion of chemical space associated with ubiquitous motifs is key to unleash new properties and functions. In this context, alkynamides, prevalent in numerous drugs and materials, represent an untapped resource. We herein report the first synthetic access to N-trifluoromethyl alkynamides. Our strategy relies on a mild and operationally simple Ni-catalyzed coupling of N-CF3 carbamoyl fluorides with alkynyl silanes. The synthesized N-CF3 alkynamides proved to be highly robust and readily functioned as a platform to unlock access to valuable derivatives, such as N-CF3 decorated alkenyl amides, oxindoles, or quinolones, all of which were inaccessible to date.

In order to discover novel compounds with inhibitory activity against 3-phosphoglycerate dehydrogenase (PHGDH), a series of thiourea derivatives were designed and synthesized based on the structural modification of compound 5d. Compound 5d emerged from the visual database of ChemDiv of 200,000 small molecules by docking score ranking. Inhibition experiments on PHGDH activity of newly synthesized compounds were performed in vitro. Compounds with more than 30percent inhibitory rate at 25?μM on PHGDH were screened for IC50 measurement. Anti-proliferative activity of 4a, 5a, 6e, 6n against A2780, MDA-MB-468, MDA-MB-231 and HEK293T in vitro was evaluated. The results showed that the compound 4a displayed the best inhibitory activity on PHGDH among the newly synthesized compounds, and the compounds 4a, 5a, 6n had a better proliferation inhibition effect on human A2780 cell line than NCT-503 reported previously. In addition, 2D interaction diagrams revealed potential action modes of active compounds with PHGDH.
