enantioselective epoxidation reaction of acyclic and cyclic 2-arylidene-1,3-diketones is reported. Easily accessible or commercially available α,α-diaryl prolinols as the organocatalysts in the presence of tert-butyl hydroperoxide (TBHP) provide the corresponding epoxides in high to excellent yield (up to 99%) and up to 85% ee (ee >90% after crystallisation). These epoxides are pharmaceutically important
Methods for treating infection and related compositions, compounds of formula I as defined in the application and methods for preparing same, are provided. In general, the compounds inhibit transfer ribonucleic acid (tRNA) synthetase and are useful as antimicrobial agents.

Regioselective vicinal difunctionalization of diverse alkene derivatives was successfully carried out using readily available carboxylic acids. Molecular oxygen in the atmospheric air tethered with the substrate to form the corresponding peroxygenated products in good yields. All the reactions were carried out at room temperature itself. Apart from the synthesis of peroxygenated products, hydroacylated
