Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, is researched, Molecular C38H24F4O4P2, CAS is 503538-69-0, about Desymmetrization of 1,4-Cyclohexadienyltriisopropoxysilane Using Copper Catalysis.Quality Control of (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole.
The first catalytic desymmetrization in the field of allylsilane chem. is presented. Desymmetrization of cyclohexadienyltriisopropoxysilane is achieved using copper catalysis. High diastereo- and enantioselectivities are obtained, and the product dienes are highly valuable building blocks for natural product synthesis.
