Directed evolution of Vibrio fischeri LuxR for increased sensitivity to a broad spectrum of acyl-homoserine lactones [PDF]
, 2005 LuxR-type transcriptional regulators play key roles in quorum-sensing systems that employ acyl-homoserine lactones (acyl-HSLs) as signal molecules.

Arkivoc, 2003 A robust and versatile kinetic alkylation-ozonolysis procedure, previously used for the synthesis of 2-alkyl-2-cyclopenten-1-ones and racemic γ-substituted-γ-lactones, has now been applied to the synthesis of chiral γ-substituted-γ-lactones and δ-substituted-δ-lactones. In addition to the synthesis of lactones with simple alkyl substituents, the method

Angewandte Chemie International Edition, Accepted Article.This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

Frontiers in Pharmacology, 2011 Atorvastatin δ-lactone, a major, pharmacologically inactive metabolite, has been associated with toxicity. In a previous study we showed that polymorphisms of UGT1A3 influence atorvastatin δ-lactone formation.

Ruthenium Catalyzed Ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts
Angewandte Chemie International Edition, EarlyView.A catalytic ortho‐arylation method has been developed to convert arylthianthrenium salts into carboxylate‐functionalized biaryls, which can be removed in situ or used for further derivatization. This reaction is broadly applicable to (hetero)arenecarboxylic acids, with excellent functional group compatibility and orthogonality to cross‐couplings ...
