Kasak, Peter published the artcileElaboration of a novel effective approach to enantiopure functionalized 2,2′-dialkyl-1,1′-binaphthyls by stereoconservative cross-couplings at positions 2 and 2′, Product Details of C22H12F6O6S2, the publication is Tetrahedron Letters (2004), 45(27), 5279-5282, database is CAplus.
The yield and the stereochem. outcome of methylation of chiral 1,1′-binaphthyl-2,2′-dielectrophiles (ditriflate and diiodide) clearly depend on the reactivity of the organometallics used. It was found that only the Negishi reaction of a diiodide allowed direct effective synthesis of non-racemic functionalized C2-sym. 2,2′-dialkyl-1,1′-binaphthyls I (R = Me, Bn, Et, CH2CH2CO2Me, CH2CH2CN).
Tetrahedron Letters published new progress about 126613-06-7. 126613-06-7 belongs to esters-buliding-blocks, auxiliary class Chiral Diphenols, name is (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), and the molecular formula is C22H12F6O6S2, Product Details of C22H12F6O6S2.
