A rhodium/photoredox dual catalyzed regiodivergent α‐allylation of amines is described. As an atom‐economic and efficient method, alkynes and allenes are used as allylic electrophile surrogates in this novel protocol. With different reaction conditions, synthetically useful branched or linear homoallylic amines could be synthesized in good to excellent yields and regioselectivity. This straightforward
A novel bifunctional organic sponge photocatalyst can enable the efficient coupling of tertiary amines with ketones in water. The asymmetric transformation can be also achieved by using this sponge photocatalyst.

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.
