Adding a certain compound to certain chemical reactions, such as: 23783-42-8, 2,5,8,11-Tetraoxatridecan-13-ol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Computed Properties of C9H20O5, blongs to alcohols-buliding-blocks compound. Computed Properties of C9H20O5
Synthesis of 2,5,8,11-tetraoxatridecan-13-ol Tosylate Procedure: (JACS, 2007, 129, 13364) To a solution of 2,5,8,11-tetraoxatridecan-13-ol (7 g, 33.6 mmol) and triethylamine (4.9 ml, 35.3 mmol) in dry CH2Cl2 (100 ml), 4-toluenesulfonyl chloride (6.7 g, 35.3 mmol) and DMAP (120 mg) were added. The mixture was stirred at room temperature for 20 h. The reaction mixture was washed with 80 mL of HCl (1M) and then water. The extract was dried over anhydrous MgSO4, filtrated, and the filtrate was evaporated. The residue was used in the next step without further purification. Yield: 11.0 g (90%) NMR: 1H NMR (400 MHz, CDCl3) delta 7.75-7.64 (m, 2H), 7.31-7.26 (m, 2H), 4.16-4.06 (m, 2H), 3.62 (m 2H), 3.59-3.40 (m, 10H), 3.30 (s, 3H), 2.38 (s, 3H). 13C{1H} NMR (101 MHz, CDCl3) delta 144.75 (s), 132.90 (s), 129.77 (s), 127.8 (s), 71.82 (s), 70.60 (s), 70.48 (s), 70.47 (s), 70.41 (s), 70.39 (s), 69.23 (s), 68.55 (s), 58.90 (s), 21.53 (s).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,23783-42-8, 2,5,8,11-Tetraoxatridecan-13-ol, and friends who are interested can also refer to it.
