(Z)-3,7-Dimethyl-2,6-octadienal - Production method
add (z)-3,7-dimethyl -2,6-octadiene -1-alcohol (nerol)(2)5.7mL(32.5mmol), acetonitrile 28mL,PH7 buffer 8mL (purchased from Fluka company),2,2,6,6-tetramethylpiperidine oxide (TEMPO)490mg(3.24mmol) into the reaction bottle equipped with a stirrer, iodobenzene diacetate 11.49g(35.71mmol). The reaction was stirred at 0 ℃ until TLC detection no longer showed the raw material absorption spots of nerol (the reaction went on very quickly, and the reaction basically ended in about 20min). Add 100mL of ether, transfer into a separatory funnel, and wash twice with sodium thiosulfate solution. The organic layer is separated, and the water layer is extracted 3 times with ether. The organic layers are combined and washed with saturated sodium bicarbonate and saturated brine in turn. Anhydrous sodium sulfate is dried, filtered, solvent is distilled under reduced pressure, the residue is purified by silica gel column, ether-hexane (1:9) is eluted, and finally colorless oily liquid (1) ① 4.30~4.39g is obtained with a yield of 87% ~ 89%.
