2-Ethynylpyrimidine (cas: 37972-24-0) belongs to pyrimidine derivatives. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Related Products of 37972-24-0

Continued development of the Sonogashira coupling has made it a well established and versatile reaction for the straightforward formation of C-C bonds, forging the carbon skeletons of broadly useful functionalized mols. However, asym. Sonogashira coupling, particularly for C(sp3)-C(sp) bond formation, has remained largely unexplored. Here the authors demonstrate a general stereoconvergent Sonogashira C(sp3)-C(sp) cross-coupling of a broad range of terminal alkynes and racemic alkyl halides (>120 examples) that are enabled by copper-catalyzed radical-involved alkynylation using a chiral cinchona alkaloid-based P,N-ligand. Industrially relevant acetylene and propyne are successfully incorporated, laying the foundation for scalable and economic synthetic applications. The potential utility of this method is demonstrated in the facile synthesis of stereoenriched bioactive or functional mol. derivatives, medicinal compounds and natural products that feature a range of chiral C(sp3)-C(sp/sp2/sp3) bonds. This work emphasizes the importance of radical species for developing enantioconvergent transformations. In the experiment, the researchers used many compounds, for example, 2-Ethynylpyrimidine (cas: 37972-24-0Related Products of 37972-24-0).
