| titleOfInvention | A class of chiral diazolobinaphthol derivatives and their synthetic methods |
| abstract | The invention discloses a class of chiral diazolo-binaphthol derivatives and a synthesis method thereof. The compound has the structure of the following formula, wherein X is O, S or Se; its preparation method: use S-/R-binaphthol as Raw materials, phenolic hydroxyl groups are protected by nitration and methyl iodide; then key intermediates are synthesized through 4‑amino‑1,2,4‑triazole; key intermediates are directly ring-closed in sodium hypochlorite, under the action of hydroxylamine hydrochloride and potassium hydroxide After deoxygenation, demethylation under the action of boron tribromide gives [6,6'-dinaphtho[1,2-c][1,2,5]oxadiazole]-7,7'diphenol. Then the key intermediate undergoes nitro reduction under the action of stannous chloride, and then ring-closing under the action of thionyl chloride and selenium dioxide respectively, and finally uses 40% hydrobromic acid and anhydrous aluminum chloride for demethylation S-/R-[6,6'-dinaphtho[1,2-c][1,2,5]thiadiazole/selenodiazole]-7,7'diol, respectively. The purpose of combining oxadiazole/thiadiazole/selenadiazole with chiral binaphthol is achieved. A series of organic compounds of the present invention broaden the range of organic photoelectric materials. |
