86% Stage #1: (R)-1-(2-hydroxy-3-(triphenylsilyl)naphthalen-1-yl)-3-(triphenylsilyl)naphthalen-2-ol With pyridine; trichlorophosphate at 95℃; for 24h; Stage #2: With water at 95℃; for 6h;
85% Stage #1: (R)-1-(2-hydroxy-3-(triphenylsilyl)naphthalen-1-yl)-3-(triphenylsilyl)naphthalen-2-ol With pyridine; trichlorophosphate at 95℃; for 24h; Inert atmosphere; Stage #2: With hydrogenchloride; water In dichloromethane
57% Stage #1: (R)-1-(2-hydroxy-3-(triphenylsilyl)naphthalen-1-yl)-3-(triphenylsilyl)naphthalen-2-ol With n-butyllithium In tetrahydrofuran at -20 - 20℃; for 2.08333h; Stage #2: With trichlorophosphate In tetrahydrofuran at 20℃; for 1.25h; Stage #3: With water; triethylamine In tetrahydrofuran for 5h; Heating / reflux; 9 Synthesis of (R)-3,3'-bis(triphenylsilyl)-1,1'-binaphthyl-2,2'-diyl hydrogenphosphate (GA11) GA10 (0.94 mmol) obtained in Synthetic example 8 and tetrahydrofuran (8 mL) were put in a two-necked round bottom flask and cooled to -20°C. To the flask, n-BuLi (2.0 mmol) was added dropwise over 5 minutes. The reaction mixture was warmed to room temperature and stirred for additional 2 hours. To the reaction mixture, a solution prepared by diluting phosphoryl chloride (1.1 mmol) in tetrahydrofuran (3.5 mL) was added dropwise over 15 minutes and the mixture was stirred at room temperature for additional 1 hour. Then, distillated water (0.4 mL) and triethylamine were added, and the mixture was heated and refluxed for 5 hours. The reaction mixture was cooled to room temperature. The solvent was distilled away under a reduced pressure. Then the 6 M hydrochloric acid (12 mL) was added. The mixture was heated and refluxed for 5 hours. The reaction mixture was cooled to 0°C and filtered. The filtrate was washed with water and dried. The obtained solid was separated from the starting materials with Hexane:Toluene=1:1 by means of column chromatography. Then the solid was eluted with toluene to give GA11 (0.54 mmol, yield: 57%). 1H-NMR(400MHz,CDCl3) δ= 8.15(d,2H,J=9.0Hz), 7.82(d,2H,J=8.2Hz), 7.66-7.60(m,12H), 7.47-7.14(m,24H).
