Chemoenzymatic Epoxidation of Alkenes and Reusability Study of the Phenylacetic Acid
The Scientific World Journal, 2014 Here, we focused on a simple enzymatic epoxidation of alkenes using lipase and phenylacetic acid. The immobilised Candida antarctica lipase B, Novozym 435 was used to catalyse the formation of peroxy acid instantly from hydrogen peroxide (H2O2) and ...

Styrene and its natural analogues: accumulation and sustainable production methods
Journal of the Science of Food and Agriculture, EarlyView.Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Synthesis of Microbial‐Derived Octadecanoids
Lipids, EarlyView.C18‐carbon containing dietary polyunsaturated fatty acids (e.g., linoleic acid, α‐linolenic acid, and γ‐linolenic acid) are metabolized by bacteria in the gut into oxygenated lipid mediators termed octadecanoids. To study the biological function of these compounds, we report here the chemical synthesis of multiple octadecanoids.

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane
Journal of Polymer Science, EarlyView.Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Lipase-mediated epoxidation of alkenes in supercritical carbon dioxide
Green Chemistry Letters and Reviews, 2018 In this work, supercritical carbon dioxide was used as reaction media in the lipase-mediated epoxidation of alkenes for the first time. Under the optimal conditions (alkene (1 mmol), novozym 435 (15 mg), H2O2 (50% aqueous solution, 1.4 mmol), n-caprylic ...
