Pushing Poly(Limonene Carbonate) Toward Commercial Applications: Bio‐Based Poly(Menth‐1‐Ene Carbonate)‐Graft‐Poly(n‐Butyl Acrylate) With Tailored Graft Density

European Journal of Lipid Science and Technology, EarlyView.
The brittleness of PLimC, which is made from limonene oxide and CO2 remains a challenge for applications. The terpolymerization of trans‐limonene oxide (LimO), trans‐menth‐1‐ene oxide (Men1O), and CO2 was shown to yield a platform for tailored graft copolymerization and was transformed into a macroinitiator for atom transfer radical polymerization ...

Terpenes and Terpenoids: How can we use them?

European Journal of Organic Chemistry, EarlyView.
The transition from petroleum‐based to renewable bio‐based chemicals has led to increased interest in terpenes and terpenoids. This overview highlights their chemistry, focusing on their reactivity and applications in polymerizations, total syntheses, pharmaceuticals, and bio‐based chemical conversions; promoting sustainable and green chemical ...

Synthesis of β‐N‐Heterocyclic‐Cyclobutane‐Fused Bicyclic γ‐Lactones from 2‐Hydroxycyclobutanone and Carboxamide‐Bearing Wittig Reagents

European Journal of Organic Chemistry, EarlyView.
The reaction of 2‐hydroxycyclobutanone with a Wittig reagent bearing a benzooxazolone moiety results in the formation of a cyclobutane‐fused bicyclic γ‐lactone with the heterocyclic unit located at the bridgehead position. The proposed mechanism involves the transfer of the acyl ylide fragment and an intramolecular Wittig reaction to provide an ...

Total Synthesis of Ectocarpin A

European Journal of Organic Chemistry, EarlyView.
A fully enantioselective total synthesis of ectocarpin A, a new oxylipin, has been achieved in 12 steps starting from tetrahydro‐1H‐cyclopentafuranone. Key steps include the formation of the chiral core, diastereoselective epoxidation, enzymatic desymmetrization of a 1,4‐diol, epimerization, and strategic Wittig and Julia‐Kocienski olefinations to ...
