Reference of 1273-94-5, 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 an article, 1273-94-5, molcular formula is C14H6FeO2, belongs to iron-catalyst compound, introducing its new discovery.
A series of ferrocene-containing mono- and bis-dihydropyrimidines (DHP’s) were prepared by boric acid mediated three-component Biginelli reactions of formyl- and 1,1?-diformylferrocene, 1,3-dioxo-components and urea. A few further transformations including hydrogenolysis of a benzyl 4-ferrocenyl-DHP-5-carboxylate were also performed. Novel cis-fused saturated pyrimido[4,5-d]pyrimidine-2,7(1H,3H)-diones incorporating [3]-ferrocenophane moiety were constructed by means of iron(III)-catalyzed Biginelli-like condensations of 1,1?-diformylferrocene with urea and in situ generated methyl ketone-derived silyl enol ethers. The structures of the new compounds were established by IR and NMR spectroscopy, including HMQC, HMBC and DEPT measurements.
Application of Biginelli reaction to the synthesis of ferrocenylpyrimidones and [3]-ferrocenophane-containing pyrimido[4,5-d]pyrimidinediones
Future efforts will undeniably focus on the diversification of the new catalytic transformations. We’ll also look at important developments of the role of 1273-94-5, and how the biochemistry of the body works.Reference of 1273-94-5
