Deconstructive Radical‐Radical Coupling for Programmable Remote Acylation

Angewandte Chemie International Edition, Accepted Article.
Dicarbonyl compounds are structural motifs that have been extensively utilized in synthetic chemistry, and their downstream transformations have proven valuable in synthesizing numerous heterocycles. Conventional methods for accessing such compounds include the Stetter reaction, the Michael reaction, and Friedel‐Crafts acylation.

Tunable Endo/Exo Selectivity in Direct Catalytic Asymmetric 1,3‐Dipolar Cycloadditions with Polyfunctional Lewis Acid / Azolium‐Aryloxide Catalysts

Angewandte Chemie International Edition, Accepted Article.
Catalytic asymmetric 1,3‐dipolar cycloadditions (1,3‐DCA) using iminoesters as ylide precursors offer a powerful approach to accessing stereochemically complex, biologically relevant pyrrolidines. While previous studies have already achieved impressive stereoselectivities, catalytic productivity remains a challenge, with turnover numbers (TON ...
