, 2016 Enantioselective alpha-deprotonation of achiral epoxides 1, 21, and 26 using organolithiums in the presence of (-)-sparteine 2 and subsequent electrophile trapping gives access to enantioenriched trisubstituted epoxides 9-17, 22, 23, 27 and 28 (in up to ...

Angewandte Chemie International Edition, EarlyView.A novel trans‐cyclooctene (TCO) based noncanonical amino acid (ncAA) is reported, characterized by high hydrophilicity and remarkable stability to trans‐cis isomerization. Its incorporation via genetic code expansion into an antibody and subsequent conjugation resulted in a highly efficacious antibody‐drug conjugate (ADC).

, 2016 Epoxides are versatile intermediates in organic synthesis, but have rarely been employed in cross-coupling reactions. We report that bipyridine-ligated nickel can mediate the addition of functionalized aryl halides, a vinyl halide, and a vinyl triflate ...

Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil
Journal of the American Oil Chemists' Society, EarlyView.This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

Catalytic Ring Opening of Epoxides by Metal Triflates: Influence of a Pending Olefin
MoleculesLewis acid-catalyzed epoxide openings efficiently promote intramolecular cyclizations forming complex oxygenated frameworks. Herein, we investigated the reactivity of epoxyolefins under catalytic conditions using various metal triflates.

Evaluation of assays for epoxides in oxidized lipids
, 2013 Epoxides have long been recognized as lipid oxidation products, and there is recent evidence that epoxides may be as or more important than hydroperoxides under many conditions.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Microalgal oil is a sustainable source of omega‐3 polyunsaturated fatty acids. However, it is very sensitive to lipid oxidation, especially in emulsions. While the presence of phospholipids and galactolipids in microalgal oil can influence its oxidation, their impact in oil‐in‐water emulsion is not yet fully understood. This study investigates

, 1997 Epoxides are versatile building blocks for organic synthesis. However, terminal epoxides are arguably the most important subclass of these compounds, and no general and practical method exists for their production in enantiomerically pure form.
