Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.

Tandem Synthesis and Photophysical Behavior of Pyrazolo[3,4‐h][1,6]naphthyridines: A Theoretical–Experimental Approach

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A tandem reaction of 5‐aroylpyrazolo[3,4‐b]pyridines with malononitrile and methanol to access pyrazolo[3,4‐h][1,6]naphthyridines was achieved in 60%–66% yield under microwave conditions. The tricyclic fluorophoric core bears groups of different stereoelectronic nature (i.e., alkyl, aryl, MeO, and CN), and thus their optoelectronic activity shows ...
