Hydroxyacetone bonds
WebWe extended the proline-catalyzed asymmetric direct aldol reactions to the TBDMS protected hydroxyacetone. This important donor provides a ready access to optically active monoprotected 1,2-diol units simultaneously accompanied by stereoselective carbon-carbon bond formation in 40–90% yield and in up to 95% WebOn the other hand it was found that for a phenol stream comprising methylbenzofuran as well as considerably amounts of hydroxyacetone e.g. up to 200 wppm methylbenzofuran and up to 1000 wppm hydroxyacetone a temperature in the last reactor below 90° C. is necessary to obtain a residual amount of methylbenzofuran below 20 wppm, preferably …

Web18 jul. 2000 · PubMed: Acetone and acetol inhibition of insulin-stimulated glucose oxidation in adipose tissue and isolated adipocytes. PubMed: The anticonvulsant activity of acetone, the major ketone body in the ketogenic diet, is not dependent on its metabolites acetol, 1,2-propanediol, methylglyoxal, or pyruvic acid. WebWith infrared spectroscopy, we have studied the interactions of four typical atmospheric OVOCs (acetone, hydroxyacetone, acetaldehyde and benzaldehyde) with model surfaces of water ice and of trihydrated nitric acid (NAT) ice. We show that these molecules weakly adsorb on water ice and NAT by hydrogen bonding.
