Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. In an article, author is Yadav, JS, once mentioned the application of 91526-18-0, Computed Properties of https://www.ambeed.com/products/91526-18-0.html, Name is 4-(Hydroxymethyl)-5-methyl-1,3-dioxol-2-one, molecular formula is C5H6O4, molecular weight is 130.0987, MDL number is MFCD12165896, category is dioxole.
We describe for the first time the free radical cyclization of enantiomerically pure alkyne-tethered aldehydes obtained from a carbohydrate (6, 7). The synthesis of compounds 6 and 7 obtained from a derivative of D-ribose is reported. These radical precursors have been submitted to cyclization with tributyltin hydride plus azobisisobutyronitrile to yield, after ring closure, two carbocycles, respectively. These carbocycles have been obtained as mixtures of E and Z vinyltin isomers, but with excellent diastereoselection at the new stereocenter formed during the ring closure. After protodestannylation, only one diastereomer was detected and isolated. The absolute configuration at the new stereocenter formed during the carbocyclization has been established by detailed H-1 NMR analysis. The specific transformation of 7-methoxymethoxy-2,2-dimethyl-4-methylene-5-tertbutyldimethylsilyloxy-(3aR,5S,7S,7aS)-perhydrobenzo[d][1,3]dioxole into optically pure (+)-allo-quercitol and (+)-talo-quercitol is described. From these results, we conclude that under an appropriate choice of radical precursors and conditions, the synthesis of highly functionalized cyclohexane derivatives of biological interest is now available.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
