Palladium-Catalyzed sp3 C–H Acetoxylation of α,α-Disubstituted α-Amino Acids

open access: yesChemistry, 2023
The sp3 C–H acetoxylation at the β-position of α,α-disubstituted α-amino acids proceeds smoothly under palladium catalysis in the presence of PhI(OAc)2. This reaction provides a straightforward synthetic route to non-natural β-acetoxy-α-amino acids.

Supercritical fluid extraction of hops [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
Five cultivars of hop were extracted by the method of supercritical fluid extraction using carbon dioxide (SFE-CO2) as extractant. The extraction (50 g of hop sample using a CO2 flow rate of 97.725 L/h) was done in the two steps: 1. extraction at 150 bar
