Electric Literature of 1198-51-2, 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, 1198-51-2, molcular formula is C9H6BrClS, introducing its new discovery.
An efficient synthesis of a potent insulin-like growth factor I receptor (IGF-IR) inhibitor AEW541 (1) is described. The key step in the synthesis is the cis-selective reductive animation of cyclobutanone, which sets up the desired 1,3-stereochemistry of the cyclobutane ring. The amino group thus generated is used as a handle to build the pyrrolopyrimidine ring. The final step resulting in 1 is accomplished by alkylation of in situ generated mesylate with azetidine.
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 1198-51-2 is helpful to your research. Electric Literature of 1198-51-2
