Electric Literature of 627-32-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 627-32-7, name is 3-Iodo-1-propanol belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a mixture of emodin (10 mmol) in dry DMF (50 mL) were added Cs2CO3 (12 mmol) and hydroxybromides or iodides (30 mmol) at room temperature. After stirring for 36 h at 60 C, the resulting mixture was evaporated under reduced pressure and then mixed with water (100 mL). The pH value of aqueous phase was adjusted to around 5 with 10% hydrochloric acid solution, extracted with dichloromethane (2 100 mL). The combined organic layer was washed with brine (200 mL), dried over anhydrous sodium sulfate and evaporated to dryness. The crude product was purified by silica gel column chromatography with 1%-10% ethyl acetate in petroleum to afford compounds 6a-6f. 1,8-Dihydroxy-3-(3-hydroxypropsoxy)-6-methylanthracene-9,10-dione (6a). According to the generalprocedure C, emodin was treated with 3-iodopropan-1-ol and then purified by silica gel columnchromatography to give compound 6a: Brown solid; yield, 55%; 1H-NMR delta 12.14 (s, 1H), 11.96 (s, 1H),7.51 (s, 1H), 7.21-7.13 (m, 2H), 6.85 (d, J = 2.5 Hz, 1H), 4.62 (t, J = 5.2 Hz, 1H), 4.23 (t, J = 6.3 Hz, 2H),3.58 (q, J = 5.9 Hz, 2H), 2.43 (s, 3H), 1.95-1.87 (m, 2H); 13C-NMR delta 189.78, 180.98, 165.53, 164.32, 161.42,148.44, 134.66, 132.69, 124.13, 120.51, 113.30, 109.60, 107.84, 106.83, 65.99, 57.00, 31.71, 21.49; ESI, m/z:329.1 [M + H]+.
The synthetic route of 3-Iodo-1-propanol has been constantly updated, and we look forward to future research findings.
