Bio‐Based Solvents Extraction and Enzyme‐assisted Recovery of Furan Fatty Acid From Ammonia‐Stabilized Hevea Latex

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The latex of Hevea brasiliensis is rich in furan fatty acid (FuFA) esterified in both neutral and polar lipids. Bio‐based solvents to extract FuFA from ammonia‐stabilized latex was tested. Ethyl acetate worked best, especially with low‐ammonia content. Isopropanol was a good alternative. Lipases could also help to efficiently release FuFA. The findings

Green Synthesis of Hantzsch Dihydropyridines from Biorenewable Furans Derived from Lignocellulosic Biomass

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A sustainable methodology is developed for the synthesis of dihydropyridines from furanic aldehydes derived from lignocellulosic biomass, using p‐sulfonic calix[4]arene as a catalyst and microwave irradiation heating. The reaction occurs in the absence of solvents, with short reaction time and satisfactory yields.
