512 g | In chloroform; at 62℃; for 6h;Inert atmosphere; | (3) Add 3.8 L of anhydrous tetrahydrofuran to the system of the step (2), and continue to add 630 g of 30% hydrogen peroxide at the above temperature. After the completion of the dropwise addition, the temperature is raised to 20 C, and stirred for 6 hours; The aqueous phase is extracted with n-hexane, and the organic phase is combined, washed with a 10% aqueous sodium carbonate solution, brine, and concentrated to remove organic solvent. Add ethanol to the concentrate, concentrate again, repeat the operation twice and then cool to 3 C. After stirring for 3 hours, the filter cake was filtered, and the filter cake was added to 6 L of chloroform. The mixture was heated to 62 C, refluxed overnight, and then distilled under reduced pressure to give trans-menthyl-2,8-dien-1-ol 512 g (purity 97.5%, ee% 99.2%, de%99.1%). The total yield of the reaction from the compound 2 (1,2-epoxylimonene) to the compound 5 (trans-menthyl-2,8-dien-1-ol) was calculated to be 67%. The total yield from the starting material 1 (limonene) to the compound 5 (trans-menthyl-2,8-dien-1-ol) was 38%. |

24% | Olivetol (920 mg, 0.00511 mol) and p-toluene sulfonic acid (PTSA) (110 mg, 0.000578 mol) were dissolved in benzene; the resulting reaction mixture azeotroped for 2.5 h. The reaction mixture was cooled to room temperature and under argon (+)-(1S,4R)-p-Mentha-2,8-dien-1-ol (586 mg, 0.00385 mol) was added and stirred at room temperature for 30 min. After completion of the reaction, the reaction mixture was diluted with diethyl ether and washed with saturated sodium bicarbonate solution. The organic layer separated and was dried on anhydrous sodium sulfate. The ether layer evaporated and purified on silica column by using petroleum ether and diethyl ether as eluent (98:2). Finally 300 mg of cannabidiol (300 mg) was collected (24percent).1HNMR (CDCl3): 6.23-6.41 (m,2H), 5.99 (s,1H,D2O exchangeable), 5.66 (s,1H), 4.56 (s,1H), 4.49 (bs,1H,D2O exchangeable) 4.46 (s,1H), 3.96 (m,1H), 2.00-2.47 (m,5H),1.87 (m,5H), 1.46-1.83 (m,6H), 1.23-1.48 (m,3H), 0.96-1.00 (m,3H). |
