(S)-(+)-1,1'-联-2-萘酚二(三氟甲磺酸酯) | (S)-2,2'-bis((trifluoromethanesulfonyl)oxy)-1,1'-binaphthyl | 128544-05-8 | C22H12F6O6S2 | 550.456 |
The performed study on the cyanation of [1,1'-binaphthalene]-2,2'-diiodide and [1,1'-binaph- thalene]-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 - affording corresponding highly enantiomerically enriched dinitrile (from diiodide: 94% yield, 92% ee). Dinitrile was successfully transformed into [1,1'-binaphthalene]-2,2'-dicarboxylic acid and -2,2'-dicarbaldehyde in high yields (84-87%).
