offers versatile control of reaction kinetics and progress. Over the past decade, many photoactive transition-metal complexes and organic chromophores were developed to catalyze chemical transformations, enabling a myriad of reactions and compounds that were previously inaccessible via traditional synthetic methods. Here, we demonstrate the photocatalytic oxidative coupling of organic thiols using cesium
Dual C–H functionalization of N-aryl tetrahydroisoquinolines: a highly diastereoselective synthesis of dibenzo[a,f]quinolizines via visible-light induced oxidation and inverse electron-demand aza-Diels–Alder reaction
Dual C–H functionalization of amines with high diastereoselectivity is developedviavisible-light photocatalysis and inverse electron-demand aza-Diels–Alder reaction.

Known and novel compounds of formula (i)
wherein E is a sulphur atom or a NH or CH2 group, J is a nitrogen atom or a CH group, Q is a sulphur atom or a NR3 or CHR3 group, Z is oxygen or sulphur atom or a NR4 or CHR4 group and R' represents four substituents and R2 represents five substituents, provided at least three of E, J, Q, and Z are methylene residues, are active against viruses, especially rhinoviruses. Methods for producing the compounds are described, as are pharmaceutical formulations and methods for administering the compounds to cure or prevent rhinoviral infections.
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.
