Chiral Potassium Brønsted Base‐Catalyzed Stereoselective Synthesis of 1,3‐Diols via a Tandem Allylic Isomerization/Asymmetric Aldol–Tishchenko Reaction

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 5, 3 March 2026.
Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Enantiospecific Optical Sensing of Terpenes by an Aggregated Atropisomeric Platinum(II) Complex

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Aggregated metal complexes act as an artificial nose and permit reversible optical sensing of small volatile molecules like R/S‐limonene based on enantiospecific recognition. Abstract Terpenes are unfunctionalized small volatile organic compounds (VOCs) that are naturally abundant, relevant to climate change, and impose potential health risks.

Cobalt‐Salen Catalysed Hydration of Alkenes With Water: A Complementary Ionic Approach to the Mukaiyama Hydration

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 5, 3 March 2026.
A cobalt‐salen catalysed hydration of olefins with water is reported, resulting in Markovnikov alcohol products. The reaction proceeds rapidly under mild conditions and exhibits excellent functional group tolerance, supporting a wide range of styrenyl and non‐activated alkenes.
