Copper (II) bromide/NMO system for α-amination of esters in solvent-free condition [PDF]
, 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.

Solvent‐Free Synthesis of Peptides [PDF]
Angewandte Chemie, 2009 A crush on sweetness ! A novel solvent-free methodology for the synthesis of peptides was developed: the coupling of an urethane protected N-carboxy anhydride (UNCA) of an aminoacid with another aminoacid derivative gave a protected dipeptide in very high yield under ball-milling conditions. The reaction is taking place in the solid state. This solvent-

Scalable solvent-free production of liposomes [PDF]
Journal of Pharmacy and Pharmacology, 2020 Abstract Objectives A major challenge faced with the manufacture of liposomes is the high volumes of organic solvents used during manufacturing. Therefore, we have implemented an organic solvent-free production method for drug-loaded liposomes and demonstrated its applicability with both aqueous core ...

Solvent‐Free Photobiocatalytic Hydroxylation of Cyclohexane [PDF]
ChemCatChem, 2020 AbstractThe use of neat reaction media, that is the avoidance of additional solvents, is the simplest and the most efficient approach to follow in biocatalysis. Here, we show that unspecific peroxygenase from Agrocybe aegerita (AaeUPO) can hydroxylate the neat model substrate cyclohexane.
