Organocatalyzed enantioselective desymmetrization of aziridines and epoxides
Enantioselective desymmetrization of meso-aziridines and meso-epoxides with various nucleophiles by organocatalysis has emerged as a cutting-edge approach in recent years.

Gold Nanoparticle-Catalyzed Environmentally Benign Deoxygenation of Epoxides to Alkenes
We have developed a highly efficient and green catalytic deoxygenation of epoxides to alkenes using gold nanoparticles (NPs) supported on hydrotalcite [HT: Mg6Al2CO3(OH)16] (Au/HT) with alcohols, CO/H2O or H2 as the reducing reagent.

The Ability of NCP@POCl2-x Core-Shell Magnetic Nano-Catalyst for Simultaneous Conversion of Epoxides into Cyanohydrin and α,β-Unsaturated Carboxylic Acid [PDF]
: This paper presents a new environmental, and remarkably efficient heterogeneous magnetic nanocomposite, NCP@POCl2-x (Fe3O4@SiO2@CS@POCl2-x), designed for the regioselective production of cyanide compounds from epoxides using NaCN, subsequently ...

One-pot synthesis of epoxides from benzyl alcohols and aldehydes
A one-pot synthesis of epoxides from commercially available benzyl alcohols and aldehydes is described. The reaction proceeds through in situ generation of sulfonium salts from benzyl alcohols and their subsequent deprotonation for use in Corey ...

Unexpected Formation of Oxetanes during the Synthesis of Dodeco-6,7-diuloses
During the synthesis of symmetrical dodeco-6,7-diuloses that are potential candidates for inhibition of glycosidases, an unanticipated epoxide-oxetane rearrangement was observed.

Water and Aqueous Mixtures as Convenient Alternative Media for Organoselenium Chemistry
Even if water is the natural environment for bioorganic reactions, its use in organic chemistry is often severely limited by the high insolubility of the organic derivatives.
