| | Methylglyoxal 1,1-dimethyl acetal Usage And Synthesis |
| Chemical Properties | clear colorless to yellow liquid | | Uses | Pyruvic Aldehyde Dimethyl Acetal is used in the preparation of MCL1 inhibitors S63845 which is tolerable and effective in diverse cancer models. Also, acts as a synthetic reagent for the preparation of 8novel 2,4-disubstituted pyrimidines as potent, selective, and cell-permeable inhibitors of neuronal nitric oxide synthase. Selective inhibition of neuronal nitric oxide synthase is an important therapeutic approach to target neurodegenerative disorders. | | Uses | Methylglyoxal 1,1-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. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 41, p. 2642, 1976 DOI: 10.1021/jo00877a030 | | Synthesis | It is produced in two main stages. Stage 1: Preparation of acetone aldehyde monohydrate. 1,2-Propanediol undergoes gas-phase oxidation over a modified electrolytic silver catalyst. Optimal conditions: temperature 350-650??C, oxygen/alcohol ratio 1.1-1.2, space velocity 18,000-20,000 h?1. Conversion is 100%, methylglyoxal selectivity is 76%. Stage 2: Preparation of Methylglyoxal 1,1-dimethyl acetal. acetone aldehyde monohydrate reacts with methanol under reflux catalyzed by a modified resin. Distillation removes low-boilers and methanol. Steam distillation gives a crude solution. Dichloromethane extraction and rectification yield the pure product. |
