Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.3458-28-4, Name is (2S,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal, SMILES is O=C[C@H]([C@H]([C@@H]([C@@H](CO)O)O)O)O, belongs to dioxoles compound. In a document, author is Shchekotikhin, A. E., introduce the new discover, Quality Control of (2S,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal.
HETEROCYCLIC ANALOGS OF 5,12-NAPHTHACENEQUINONE 8. SYNTHESIS OF FURANO-ANTHRAQUINONES
During the condensation of 2,3-dichloroquinizarine with methyl pivaloylacetate in the presence of potassium carbonate in dimethyl sulfoxide the main reaction products are derivatives of angular 3-pivaloylanthra[1,2-b]furan-2,6,11(3H)-trione (about 70%) and anthra[2,1-d][1,3]dioxole-6,11-dione (15%), whereas the yield of the targeted linear methyl 2-tert-butyl-4,11-dihydroxyanthra[2,3-b]furan-5,10-dione-3-carboxylate is only 2%. Methods are developed for modification of the obtained 3-pivaloylanthra[1,2-b]furan-2,6,11(3H)-trione, making it possible to use it for the synthesis of the tertbutyl derivatives of linear anthra[2,3-b]furan-5,10-dione or angular anthra[1,2-b]furan-6,11-dione.
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 3458-28-4 is helpful to your research. Quality Control of (2S,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal.
