Related Products of 13395-16-9, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 13395-16-9, molcular formula is C10H16CuO4, introducing its new discovery.
Desymmetrization of meso-N-sulfonylaziridines with chiral nonracemic nucleophiles and bases
The cyclohexene-derived aziridine 7-tosyl-7-azabicyclo[4.1.0]heptane (1) reacts with Grignard reagents in the presence of chiral nonracemic Cu-catalysts to afford sulfonamides 3a-e in up to 91% ee under optimized conditions. No activation of the aziridine by Lewis acids is required. The reaction may be extended to other bicyclic N-sulfonylated aziridines, but aziridines derived from acyclic olefins, cyclooctene, and trinorbornene are unreactive under standard conditions. Exposure of 1 to s-BuLi in the presence of (-)-sparteine (2.8 equiv.) affords the allylic sulfonamide 31 in 35% yield and 39% ee. Under the same conditions, the aziridines 33 and 35 yield products 34 and 36 derived from intramolecular carbenoid insertion with 75 and 43% ee, respectively.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13395-16-9 is helpful to your research. Related Products of 13395-16-9
