Total Synthesis of Novel Oxylipins: Plasmodiophorols A, C, and Epimers

European Journal of Organic Chemistry, EarlyView.
The first total syntheses of plasmodiophorols A and C, recently identified α‐linolenic acid‐derived oxylipins, were achieved from chiral cyclopentafuranone in 12–13 steps. The routes use enzymatic desymmetrization, epimerization, and diastereoselective Grignard addition, providing stereocontrolled access to the natural products and reliable standards ...

Vegetable-Oil-Based Hyperbranched Polyester-Styrene Copolymer Containing Silver Nanoparticle as Antimicrobial and Corrosion-Resistant Coating Materials

Journal of Chemistry, 2013
Pongamia oil (PO) was converted to Pongamia oil hydroxyl (POH) via epoxidation process. The esterification of POH with linolenic acid was carried out to form hyperbranched polyester (HBPE), and further styrenation was performed at the conjugated double ...

Modification of Titania and Iron Oxide Pigments for Application in Photoinitiated Cationic Polymerization of Epoxidized Linseed Oil

Applied Research, Volume 5, Issue 2, April 2026.
Surface modification of titania and diverse iron oxide particles was made by silanization or using starch laurate or a polymer made by miniemulsion polymerization of a bio‐based monomer. This facilitates the photoinitiated cationic polymerization of epoxidized linseed oil using a UV LED. ABSTRACT The surface of titania, iron oxide red, iron oxide black,

Engineering membrane‐bound alkane monooxygenase from Marinobacter sp. for increased activity in the selective ω‐hydroxylation of linear and branched aliphatic esters

Protein Science, Volume 35, Issue 4, April 2026.
Abstract The regio‐ and stereoselective hydroxylation of unactivated C(sp3)‐H bonds is an important reaction in organic synthesis. While bacterial alkane monooxygenase AlkB catalyzes the terminal hydroxylation of aliphatic esters with excellent regioselectivity, the molecular principles of substrate recognition and selectivity of this integral membrane
