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

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

Engineering of an Ancestral McbA with Enhanced Domain Mobility Extends Biocatalytic Amide Synthesis Scope

Advanced Synthesis &Catalysis, EarlyView.
We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.
