fundamental motif in synthetic chemistry, playing a critical role in metal-mediated cross-coupling reactions and serving as important scaffolds in drug discovery. Although thermal decarboxylative functionalization of aryl carboxylic acids has been extensively explored, the scope of existing halodecarboxylation methods remains limited, and there currently exists no unified strategy that provides access to

The incorporation of the trifluoromethoxy group into organic molecules has become very popular due to the unique properties of the named substituent that has a “pseudohalogen” character, while the chemical properties of the synthesized compound, especially heterocycles with such a group, are less studied. As trifluoromethoxy-substituted pyrazines are still unknown, we have developed efficient and scalable

A nitrogen-containing polycyclic fused ring compound of formula I, a pharmaceutical composition thereof, a preparation method therefor and use thereof are related to the field of medicinal chemistry. The compound can be used as a selective and effective RET inhibitor. It has strong inhibitory effect on the RET gatekeeper residue mutant RET V804M, RET solvent-front residue mutant RET G810R and other clinically relevant RET mutants, as well as RET wt. The compound can also inhibit the growth of TT cell line derived from thyroid cancer and Ba/F3 cells transformed with various RET mutants, and induce the death of TT cells.
