Large-Scale Preparation of N-Butanoyl- l -glutathione (C4-GSH)

A novel two-step synthesis of N-butanoyl-l-glutathione (C4-GSH) was developed involving the chemical modification of the commercially available starting material l-glutathione (GSH). This process not only has the advantage of selective acylation of the GSH amino group without the use of previous solid-phase organic synthesis and/or protecting group chemistry but also highlights the use of inexpensive reagents such as butyric anhydride and sodium methoxide as well as environmentally acceptable solvents such as water and methanol. This chromatography- and salt-free synthesis of C4-GSH is cost-effective, safe, efficient, and easy to scale up.

Deoxyfluorination of Carboxylic Acids with KF and Highly Electron-Deficient Fluoroarenes

A deoxyfluorination reaction of carboxylic acids using potassium fluoride (KF) and highly electron-deficient fluoroarenes is reported here, giving acyl fluorides in moderate to excellent yield (57-92% based on NMR integration and 34-95% for isolated examples).

Homogeneous catalytic hydrogenation of perfluoro methyl esters

The first example of perfluoroalkyl methyl ester RfC(O)OMe (Rf = C3F7, C5F11) reduction by homogeneous catalytic hydrogenation with the ruthenium catalyst Ru-MACHO is herein reported. The hydrogenation process leads to the corresponding perfluorinated alcohols thus replacing sodium borohydride that has so far represented the state of art in perfluoro ester reduction.
