Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with a defect in glyoxylate metabolism, for example a disease or disorder associated with the enzyme glycolate oxidase (GO) or alterations in oxalate metabolism. Such diseases or disorders include, for example, disorders of glyoxylate metabolism, including primary hyperoxaluria, that are associated with production of excessive amounts of oxalate.

The reduction of a variety of functional groups with the nickel(II) chloride-zinc system was investigated. This system reduced aldehydes, ketones, olefins, nitriles, oxime, nitro and heterocyclic compounds under mild conditions in good yields. It is of interest that some cases of reduction of ketones afforded the corresponding olefins and the saturated products, and the reduction of nitriles afforded the corresponding primary alcohols with the primary and secondary amines. The selective reduction of olefin and nitro functionalities in some compounds bearing carbonyl, ester and carboxyl functionalities was observed with this system.

Selectiveruthenium-catalyzed reductive coupling of primary amides under hydrosilylation conditions is achieved using an one pot procedure. Using 3 equiv. of phenylsilane and [RuCl2(mesitylene)]2 (1-2 mol%) as the catalyst at 100 degrees C under neat conditions, secondary symmetric amines were obtained in good yields and with high chemoselectivities.

The invention relates to a method for producing a N-substituted amine compound by catalyzed alkylation. The method uses amine and alcohol or two kinds of amines as the reaction materials, employs composite metal oxides catalyst at a reaction temperature of 80-180° C. to catalyze the reaction for 6-36 hours, so as to produce the N-substituted amine compound. The reaction condition of the method of the invention is relatively moderate, using a catalyst made of cheap non-noble metals, which is non-caustic and easy to be separated and reused. The reaction does not need any medium and has relatively high conversion rate and selectivity.
