1. Manganese-catalysed transfer hydrogenation of esters.

Author

Oates, Conor L., Widegren, Magnus B., and Clarke, Matthew L.

Subjects
*TRANSFER hydrogenation, *ESTERS, *CATALYSTS, *MANGANESE
Abstract

Manganese catalysed ester reduction using ethanol as a hydrogen transfer agent in place of dihydrogen is reported. High yields can be achieved for a range of substrates using 1 mol% of a Mn(I) catalyst, with an alkoxide promoter. The catalyst is derived from a tridentate P,N,N ligand. [ABSTRACT FROM AUTHOR]

2. A consecutive process for C–C and C–N bond formation with high enantio-and diastereo-control: direct reductive amination of chiral ketones using hydrogenation catalysts.

Author

Gilbert, Sophie H., Viseur, Virginie, and Clarke, Matthew L.

Subjects
*AMINATION, *KETONES, *HYDROGENATION, *CATALYSTS, *CATALYSIS, *TERTIARY amines
Abstract

High diastereoselectivity was observed in the Rh-catalysed reductive amination of 3-arylcyclohexanones to form tertiary amines. This was incorporated into a one-pot enantioselective conjugate addition and diastereoselective reductive amination, including an example of assisted tandem catalysis. [ABSTRACT FROM AUTHOR]

3. Catalytic constructive deoxygenation of lignin-derived phenols: new C-C bond formation processes from imidazole-sulfonates and ether cleavage reactions.

Author

Leckie, Stuart M., Harkness, Gavin J., and Clarke, Matthew L.

Subjects
*OXIDATION of phenols, *CARBON-carbon bonds, *CHEMICAL synthesis, *IMIDAZOLES, *SULFONATES, *ETHER synthesis, *SCISSION (Chemistry), *LIGNIN structure, *GRIGNARD reagents
Abstract

As part of a programme aimed at exploiting lignin as a chemical feedstock for less oxygenated fine chemicals, several catalytic C-C bond forming reactions utilising guaiacol imidazole sulfonate are demonstrated. These include the cross-coupling of a Grignard, a non-toxic cyanide source, a benzoxazole, and nitromethane. A modified Meyers reaction is used to accomplish a second constructive deoxygenation on a benzoxazole functionalised anisole. [ABSTRACT FROM AUTHOR]
