Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2615-15-8, name is 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol. This compound has unique chemical properties. The synthetic route is as follows. 2615-15-8
j00479j A solution of 3,6,9,12,15-pentaoxaheptadecane-1,17-diol (7 g, 24.8 mmol) in DCM (50 mL) was cooled to 0 C and charged with silver oxide (8.60 g, 37.2 mmol), potassium iodide (822 mg, 4.95 mmol) and tosyl chloride (5.10 g, 27.17 mmol) and stirred at0C for 4 h. The reaction mixture was diluted with iN HC1 solution (15 mL), the organic layers was separated and dried over anhydrous Na2SO4, filtered and concentrated in vacuo resulting in a crude compound which was purified by chromatography on silica gel, eluting with 1-3% methanol in DCMto give 7.30 g, 67% yield of the title compound as colorless oil. ?H NMR (400 MHz, DMSO-d6): oe = 7.79 (d, J= 8.43 Hz, 2H), 7.48 (d, J= 7.98 Hz, 2H), 4.56 (t, J= 5.54 Hz, 1H), 4.08 -4.14 (m, 1H), 3.43 -3.59 (m, 20H), 3.41 (d, J= 5.32 Hz, 2H), 3.39 (s, 1H), 2.42 (s, 3H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,2615-15-8, 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol, and friends who are interested can also refer to it.
