Dynamic “Deactivation” mechanism enables epoxides ring-opening to prepare α-substituted alcohols

Nature Communications
The selective synthesis of α-substituted alcohols from epoxides remains challenging. A promising strategy involves Lewis acid (LA)-catalyzed Meinwald rearrangement of epoxides, followed by 1,2-addition to in situ–generated aldehydes.

Epoxides and Soluble Epoxide Hydrolase in Cardiovascular Physiology [PDF]

Physiological Reviews, 2012
Epoxyeicosatrienoic acids (EETs) are arachidonic acid metabolites that importantly contribute to vascular and cardiac physiology. The contribution of EETs to vascular and cardiac function is further influenced by soluble epoxide hydrolase (sEH) that degrades EETs to diols. Vascular actions of EETs include dilation and angiogenesis.

Effective One-Component Organocatalysts for Eco-Friendly Production of Cyclic Carbonates

Reactions
One-component or bifunctional organocatalysts are some of the most capable compounds to perform the synthesis of cyclic carbonates from epoxides and carbon dioxide (CO2) since the presence of a co-catalyst is not required.
