The metal-catalyzed alkoxycarbonylation of a lactone is a method of alkoxycarbonylating a -lactone, specifically 3-ethylidene-6-vinyltetrahydro-2H-pyran-2-one. The method includes combining the -lactone with an alcohol in an organic solvent in the presence of a catalyst system that includes palladium or a salt thereof to form a reaction mixture, which is heated to 110-130 C. at a pressure of 20-50 bar for between 3-5 hours under flow of carbon monoxide gas. The product of the reaction is a substituted 2-octendioate diester. The alcohol may be methyl alcohol, n-butyl alcohol, 2-ethylhexanol, isobutyl alcohol, isopropyl alcohol, benzyl alcohol, or phenol. The solvent may be toluene, acetonitrile, or tetrahydrofuran. The method may include adding an acid to the reaction mixture, which may be dilute (about 5 mol %) sulfuric or p-toluenesulfonic acid. The catalyst system may also include a phosphine ligand.

The present disclosure provides processes for producing alkylated fatty acids and derivatives thereof. In at least one embodiment, a process includes introducing a terminal alkyl transferase and a fatty acid into a bioreactor. The process includes introducing an internal methyl transferase and internal methyl reductase into the bioreactor or a second bioreactor. The process includes obtaining an alkylated fatty acid having a methyl substituent located at an internal carbon atom of the fatty acid and a methyl substituent or ethyl substituent located at a carbon atom alpha to the terminal carbon atom of the fatty acid.
