A straightforward approach towards combined α-amino and α-hydroxy acids based on Passerini reactions
Complex amino acids with an α-acyloxycarbonyl functionality in the side chain are easily available through epoxide opening by chelated enolates and subsequent oxidation/Passerini reaction. This protocol works with both, aldehyde and ketone intermediates,

Anti-bacterial screening and sequential synthesis of 1,2,3-triazoles âfrom alcohols and epoxides in water [PDF]
The triazole core is an important part of the therapeutically drugs such as antimicrobial, analgesic and anti-inflammatory agents. Therefore, a facile synthesis of a series of 1,2,3-triazoles has been introduced by the sequential azidation of alcohols or

Valorization of CO2 through the Synthesis of Cyclic Carbonates Catalyzed by ZIFs
One way to exploit CO2 is to use it as a feedstock for the production of cyclic carbonates via its reaction with organic epoxides. As far as we know, there is still no heterogeneous catalyst that accelerates the reaction in a selective, efficient and ...
