The hydrogen transfer mechanism of cofactor reduction and recycling processes in the yeast reduction of α,β-unsaturated ketone was studied by using quantitative isotope tracing close to natural abundance measured by 2H NMR. In the reaction, the active cofactor is NADPH. The cofactor-transferred hydr...
The condensation reaction of formylferrocene with simple aliphatic and alicyclic ketones, as acetone, ethyl methyl ketone, isobutyl methyl ketone, and cyclohexanone, in the presence of piperidine as a condensing agent afforded seven kinds of β-ferrocenyl-α,β-unsaturated ketones. The geometric ...
