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 ...

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.

Previously unknown 4,5-epoxy-N-acetyl-sphingosine (1) was synthesized by epoxidation of N-acetyl-sphingosine with 1,1-dimethyldioxirane. A by-product generated by HPLC purification is the tetrahydrofuryl derivative of acetamide (2). Mainly allylic oxidation was observed when natural ceramides were reacted with dimethyldioxirane.

SDN opens a new chapter in network troubleshooting as besides misconfigurations and firmware/hardware errors, software bugs can occur all over the SDN stack. As an answer to this challenge the networking community developed a wealth of piecemeal SDN troubleshooting tools aiming to track down misconfigurations or bugs of a specific nature (e.g.

Epoxide hydrolase activity is recovered in the high-speed supernatant fraction from the liver of all mammals so far examined, including man. For some as yet unexplained reason, the rat has a very low level of this activity, so that cytosolic epoxide hydrolase is generally studied in mice.

Aliphatic Epoxide Carboxylation
Annual Review of Biochemistry, 2003▪ Abstract Aliphatic epoxides (epoxyalkanes) are highly reactive electrophilic molecules that are formed from the monooxygenase-catalyzed epoxidation of aliphatic alkenes. The bacterial metabolism of short-chain epoxyalkanes occurs by a three-step pathway resulting in net carboxylation to β-ketoacids.

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).
