14098-24-9, Benzo-18-crown 6-Ether is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: A modification of the previously reported procedure23 was used. Commercially available Eaton’s reagent (ca. 8 ml that corresponds to 6.28 mmol of phosphorus(V) oxide) and acetic acid (0.20 ml, 3.45 mmol) were mixed at room temperature. Then naphtho-15-crown-5 ether (1 g, 3.14 mmol) was added. The reaction mixture was stirred at room temperature for ca. 6 h and then poured into water. The suspension was extracted with dichloromethane and the combined organic phases were washed with water. Removal of the dried (MgSO4) solvent gave a dark brown oil, which upon repeated extractions with hot heptane, afforded the product as an off-white solid (1.02 g, 90%), mp 126-129 C., 14098-24-9
The synthetic route of 14098-24-9 has been constantly updated, and we look forward to future research findings.
