Enantioselective Conjugate Addition of Malononitriles to Enynes: A Stereodivergent Approach to Chiral Allenes

European Journal of Organic Chemistry, EarlyView.
Quinine‐catalyzed enantioselective conjugate addition of malononitrile derivatives to enynes provides trisubstituted chiral allenes in good to excellent yields and high enantiopurities under mild conditions. Broad substrate scope, easy scalability, and versatile post‐synthetic transformations into enantioenriched pyrazoles and furans highlight the ...

Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones

European 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

European 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 ...

Synthesis of α‐C‐Glycoside Conjugates Promoted by 4CzIPN‐Based Porous Organic Polymers Through Giese‐Like Reaction of Glycosyl Bromides in Batch and Continuous Flow

European Journal of Organic Chemistry, EarlyView.
Visible light and a 4CzIPN‐based porous organic polymer (4CzIPN‐POP) enable Giese‐like coupling of glycosyl bromides with electron‐poor alkenes to access α‐C‐glycoside conjugates. The study shows how heterogeneous thermally activated delayed fluorescence photocatalysis can be combined with continuous flow to overcome light penetration limits and ...
