Anwendungen

Pyruvic aldehyde dimethyl acetal was used in the synthesis of methylglyoxal via hydrolysis in the presence of H2SO4. It was used to investigate the effects of methylglyoxal-mediated glycation on the structure, thermal stability and enzyme activity of yeast enolase in vivo.

Bemerkungen

Do not store together with acids. Store in cool place. Keep container tightly closed in a dry and well-ventilated place.

The cyclohexylimine or the N,N-dimethylhydrazone can be lithiated at the methyl group with LDA to give useful synthetic species capable of alkylation, etc.: Synthesis, 198 (1977). For a review of the alkylation of nitrogen derivatives of carbonyl compounds, see: Synthesis, 517 (1983).
