CBr<sub>4</sub> as a Mild Oxidant‐Enabled Oxidation of a <i>sp</i><sup><i>3</i></sup> C−H Bond: A Facile Synthesis of the Persistent Iminium Salts of Tetrahydroisoquinolines
A C−H bond oxidation of THIQs was achieved by CBr4 initiated reaction conditions, providing a series of the persistent iminium salts of THIQs in high yields with good functional group tolerance. These iminium salts can be readily applied to the synthesis of the functionalized THIQ derivatives.
Photocatalytic α-C(sp3)–H pyridination of N-arylglycine derivatives and N-arylamines with cyanopyridines was developed through radical–radical cross-coupling under redox-neutral conditions.
Solvent-driven C(sp<sup>3</sup>)–H thiocarbonylation of benzylamine derivatives under catalyst-free conditions
(QM) computations and well-designed experiments on the reaction mechanism revealed that this thiocarbonylation depends on the specific solvent that initially drives this reaction through the intermolecular hydrogen atom transfer (HAT). And the following single electrontransfer (SET) induces the electron-catalyzed C–S bond formation and intramolecular HAT realizing the final establishment of the CS bond
Discovery of N-substituted oseltamivir derivatives as novel neuraminidase inhibitors with improved drug resistance profiles and favorable drug-like properties
To yield potent neuraminidase inhibitors with improved drug resistance and favorable drug-like properties, two series of novel oseltamivir derivatives targeting the 150-cavity of neuraminidase were designed, synthesized, and biologically evaluated. Among the synthesized compounds, the most potent compound 43b bearing 3-floro-4-cyclopentenylphenzyl moiety exhibited weaker or slightly improved inhibitory
