A Very Important Paper has been published by I. Kulašić, B. Štefane and co-workers in Advanced Synthesis & Catalysis.
The cover illustrates novel wavelength-dependent transformations of pyrazolo[1,2-a]pyrazolones into 3D-rich heterocyclic systems. The robot with flashlights represents how two distinct products can be easily obtained by simply adjusting the irradiation wavelength, leading to either 1,2-diazepines through ring expansion or tricyclic product via consecutive 4π-electrocyclization. These transformations are highly stereoselective, do not require photocatalysts or additives, and can be easily scaled up.
Congratulations for this outstanding achievement!
