Rh‐Catalyzed Chemodivergent Parallel Kinetic Resolution and Desymmetrization of Enynes and Dienynes with Acrylamides

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Rh‐catalyzed chemodivergent parallel kinetic resolution of racemic 1,6‐enynes with α‐fluoroacrylamides or mixtures of different acrylamides proceeded via [2+2+2] cycloaddition and C–H alkylation to afford structurally and stereochemically distinct products with high selectivity under mild conditions.

Stereoselective Chemoenzymatic Synthesis Metaraminol Involving Gold‐Catalysed Alkyne Hydration and Carbonyl Biotransamination

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A chemoenzymatic synthesis of (1R,2S)‐metaraminol was developed by combining gold(I)‐catalysed alkyne hydration and stereoselective biotransamination in a sequential one‐pot process. Various phenol protection strategies were considered in oxidation‐reduction sequences, providing access to enantiopure propargylic alcohols as starting materials for ...

Enantioselectivity in Transition Metal Catalyzed Propargylic Substitution Reactions: A Theoretical Perspective

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Recent theoretical efforts to elucidate the origin of enantioselectivity in transition metal‐catalyzed propargylic substitution reactions are highlighted in this review. ABSTRACT In recent years, asymmetric catalytic propargylic substitution reactions have undergone remarkable development, enabling the construction of chiral carbon centers adjacent to ...

Silyl Rearrangements in Gold‐Catalyzed Transformations

European Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
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.
