Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.63-37-6, Name is 5′-Cytidylic acid, SMILES is O=P(O)(OC[C@@H]1[C@H]([C@H]([C@H](N2C(N=C(C=C2)N)=O)O1)O)O)O, belongs to benzodioxans compound. In a document, author is Mironov, Vladimir F., introduce the new discover, Safety of 5′-Cytidylic acid.
The reaction of 4-(1,3,2-benzodioxaphosphol-2-yloxy)-3-tert-butylpent-4-en-2-one with hexafluoroacetone
Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.
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 63-37-6 is helpful to your research. Safety of 5′-Cytidylic acid.
