Glucosylation of Sucrose Laurate with Cyclodextrin Glucanotransferase [PDF]

open access: yes, 2007
Sucrose monolauroyl esters were found to serve as substrates for cyclodextrin glucanotransferase (CGTase)-catalyzed transglucosidation reactions, affording new sucrose esters that have an additional 1-3 glucose residues on the pyranose ring of the ...

Disruption of Crystal Packing in Thieno[2,3-b]pyridines Improves Anti-Proliferative Activity

open access: yesMolecules, 2022
3-Amino-2-arylcarboxamido-thieno[2,3-b]pyridines have been shown to have anti-proliferative activity, but are also known to have poor solubility. This has been previously proposed to be due to their extensive planarity, which allows for intermolecular ...

Copper (II) bromide/NMO system for α-amination of esters in solvent-free condition

open access: yes, 2023
Copper (II) bromide/ N-methylmorpholine N-oxide promoted α-amination of esters in solvent-free condition is reported. The α-amino esters are precursors for α-amino acids. This method provides α-amino esters in 58-83% yields.
