Deamination of serine. I. Catalytic deamination of serine and cysteine by pyridoxal and metal salts.
In an investigation of transamination reactions between pyridoxal and amino acids at 100” (2) serine was found to behave anomalously, apparently being deaminated to pyruvic acid with little change in pyridoxal concentration. Although serine is known to be deaminated by hot concentrated alkalies (3) and acids (4), such a non-enzymatic reaction in the pH range near neutrality has not been reporte...
متن کاملOxidative deamination of azafulleroids into C60 by peracids.
Oxidation of azafulleroids with peracids regenerated C60 depending on the N-substituents. Alkyl-substituted azafulleroids preferred the oxidation of nitrogen to afford N-oxides as possible intermediates for C60 in moderate yields. Phenyl- and tosyl-substituted azafulleroids rather allowed the oxidation at the carbon cage. Theoretical calculations predicted the order of reactivity of azafulleroi...

متن کاملHeterolytic H2 Cleavage and Catalytic Hydrogenation by an Iron Metallaboratrane.
Reversible, heterolytic addition of H2 across an iron-boron bond in a ferraboratrane with formal hydride transfer to the boron gives iron-borohydrido-hydride complexes. These compounds catalyze the hydrogenation of alkenes and alkynes to the respective alkanes. Notably, the boron is capable of acting as a shuttle for hydride transfer to substrates. The results are interesting in the context of ...
متن کاملCatalytic stereodivergent functionalization of H2@C60.
A complete stereocontrol of 1,3-dipolar cycloaddition of N-metalated azomethine ylides onto endohedral fullerene H2@C60 is reported for the first time. The stereodivergent synthesis of either the cis or the trans endohedral cycloadduct is achieved with excellent diastereo- and enantioselectivities.
