The Ru(II)-catalyzed hydrogenation of α-amino-β-keto esters as their hydrochloride salts affords preparation of the corresponding anti
α-amino-β-hydroxy esters under mild conditions with high diastereoselectivities and enantioselectivities via dynamic kinetic resolution.
anti-α-amino β-hydroxyesters with high levels of selectivity by the use of Ru-SYNPHOS® catalysts is reported. The key transformations include asymmetric hydrogenations of α-N-substituted β-keto esters protected as α-amido or α-amino hydrochloride derivatives, respectively. The RuII-catalyzed hydrogenation of α-amino β-keto ester hydrochlorides affords the corresponding anti-α-amino β-hydroxyesters with high

Arylcycloalkyl-substituted alkanoic acid derivatives, processes for their preparation and their use as pharmaceuticals
The invention relates to arylcycloalkyl-substituted alkanoic acid derivatives and to their physiologically acceptable salts and physiologically functional derivatives.
What is described are compounds of the formula I,
1
in which the radicals are as defined, and their physiologically acceptable salts and processes for their preparation. The compounds are suitable, for example, for the treatment and/or prevention of disorders of the fatty acid metabolism and glucose utilization disorders and also disorders in which insulin resistance is involved.
