Selective aliphaticC-H bond oxidations may have a profound impact on synthesis because these bonds exist across all classes of organic molecules. Central to this goal are catalysts with broad substrate scope (small-molecule-like) that predictably enhance or overturn the substrate's inherent reactivity preference for oxidation (enzyme-like). We report a simple small-molecule, non-heme iron catalyst that
This invention relates to a range of alpha substituted 2-benzyl substituted imidazole compounds and pharmaceutically acceptable salts and solvates thereof, to compositions comprising such compounds, processes for their synthesis and their use as parasiticides.

The invention provides simple small molecule, non-heme iron catalyst systems with broad substrate scope that can predictably enhance or overturn a substrate's inherent reactivity preference for sp3-hybridized C—H bond oxidation. The invention also provides methods for selective aliphatic C—H bond oxidation. Furthermore, a structure-based catalyst reactivity model is disclosed that quantitatively correlates the innate physical properties of the substrate to the site-selectivities observed as a function of the catalyst. The catalyst systems can be used in combination with oxidants such as hydrogen peroxide to effect highly selective oxidations of unactivated sp3 C—H bonds over a broad range of substrates.
Lipase-catalyzedtransesterifications of cis- and trans-4-methylcyclohexanols with vinyl acetate in various organicsolvents have been studied, and the effect of solvent on activity and stereoselectivity of lipase has been investigated. Initial rate of the reaction increases with the increase in hydrophobicity of the solvent exerting a good correlation with logP', a corrected index of logP. However
