Epoxide Electroreduction

Journal of the American Chemical Society, 2021
Selective hydrogenation of epoxides would be a direct and powerful approach for alcohol synthesis, but it has proven to be elusive. Here, electrochemically epoxide hydrogenation using electrons and protons as reductants is reported. A wide range of primary, secondary, and tertiary alcohols can be achieved through selective Markovnikov or anti ...

Estimation of Epoxides [PDF]

Nature, 1949
EPOXIDES occur among the products of the autoxidation of unsaturated fatty acids1 and drying oils2, and it has been suggested that they may be formed as intermediates in certain biological oxidations. Their accurate estimation is therefore a matter of considerable importance.

The interaction of cytosolic epoxide hydrolase with chiral epoxides

International Journal of Biochemistry, 1993
1. The kinetic parameters of the cytosolic epoxide hydrolase were examined with two sets of spectrophotometric substrates. The (2S,3S)- and (2R,3R)-enantiomers of 4-nitrophenyl trans-2,3-epoxy-3-phenylpropyl carbonate had a KM of 33 and 68 microns and a Vmax of 16 and 27 mumol/min/mg, respectively.

Graphite Epoxide

Journal of the American Chemical Society, 2008
Oxidation of graphite may be carried out by reaction with meta-chloroperoxybenzoic acid to yield graphite epoxide. Scanning tunneling microscopy (STM) showed that the functionalization occurs at the edges rather than on the basal plane of the graphite.

Reactions of epoxides—I

Tetrahedron, 1964
Abstract New preparative routes to the 13α,17aα-epoxide (II) and the 13β,17aβ-epoxide (III) are described. Boron trifluoride in benzene converts the α-epoxide (II) into a mixture from which five products were isolated, but the β-epoxide (III) gives only the 17aβ-hydroxy-Δ8(14)-olefin (VIII).
