Manganese Catalyzed Hydrogenation of Enantiomerically Pure Esters
Widegren, Magnus B.,Clarke, Matthew L.
supporting information, p. 2654 - 2658 (2018/05/17)
A manganese-catalyzed hydrogenation of esters has been accomplished with TONs up to 1000, using cheap, environmentally benign, potassium carbonate and simple alcohols as activator and solvent, respectively. The weakly basic conditions lead to good functional group tolerance and enable the hydrogenation of enantiomerically enriched α-chiral esters with essentially no loss of stereochemical integrity.

, p. 345 - 348 (2007/10/03)
Desymmetrization of dimethyl meso-piperidine-3,5-dicarboxylates 3a-c with pig liver esterase (PLE), lipase from Candida cylindracea (CCL) and porcine pancreatic lipase (PPL) is described. The enantioselectivities of the enzymatic transformations and the absolute configurations of the resulting half-esters 2a-c were determined.
