Kasak, Peter published the artcileStereoconservative cyanation of [1,1′-binaphthalene]-2,2′-dielectrophiles. An alternative approach to homochiral C2-symmetric [1,1′-binaphthalene]-2,2′-dicarbonitrile and its transformations, HPLC of Formula: 126613-06-7, the publication is Collection of Czechoslovak Chemical Communications (2000), 65(5), 729-740, database is CAplus.
Cyanation of [1,1′-binaphthalene]-2,2′-diiodide and [1,1′-binaphthalene]-2,2′-diyl ditriflate showed reactions with zinc cyanide catalyzed by palladium phosphane complex in DMF to be the most effective procedures with almost complete conservation of stereogenic information by affording a corresponding highly enantiomerically enriched dinitrile (from diiodide in 94% yield, 92% ee). The dinitrile was successfully transformed into [1,1′-binaphthalene]-2,2′-dicarboxylic acid and -2,2′-dicarbaldehyde in high yields (84-87%).
Collection of Czechoslovak Chemical Communications 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, HPLC of Formula: 126613-06-7.
