Advanced Synthesis &Catalysis, EarlyView.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

Aerobic Oxidative Dethioacetalization Catalyzed by an Iron Phthalocyanine Complex
Advanced Synthesis &Catalysis, EarlyView.A protocol for iron octacarboxyphthalocyanine‐catalyzed aerobic oxidative dethioacetalization in an aqueous solvent is developed. This method can efficiently convert a broad range of dithioacetals into the corresponding carbonyl compounds. Inspired by enzyme‐mediated redox processes, the environmentally friendly catalytic system exhibits remarkable ...

Advanced Synthesis &Catalysis, EarlyView.A nickel catalyzed three‐component coupling reaction between an aldehyde, a secondary amine, and butadiene allows a straightforward access to 5‐aminopent‐3‐en‐1‐ol scaffolds according to a salt‐free process. Key steps are oxidative coupling reaction between one aldehyde, one butadiene on a low valent nickel precursor, and the nucleophilic attack of a ...

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes
Advanced Synthesis &Catalysis, EarlyView.The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.
