EDA Complex–Mediated C(sp3)–H Cross‐Dehydrogenative Coupling Enables Synthesis of Noncanonical α,β‐Diamino Acids

European Journal of Organic Chemistry, EarlyView.
Access to nonproteinogenic α,β‐diamino acids from simple feedstock precursors is of great interest to generate medicinal small molecule libraries. We report a regioselective photoinduced C(sp3)–C(sp3) cross‐dehydrogenative coupling (CDC) of N‐arylglycine derivatives with amides.

Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

European Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

Silyl Rearrangements in Gold‐Catalyzed Transformations

European Journal of Organic Chemistry, EarlyView.
The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.
