分子式C15H14O31.187±0.06 g/cm³ (Predicted)沸点391.2±27.0 °C (Predicted) 溶解度0.0423 mg/ml;0.000175 mol/l 酸度系数(pKa)10.52±0.20 (Predicted) 路线2:
步骤:将2',5'-羟基苯乙酮(7.60g,0.05mol),无水碳酸钾(8.00g,0.06mol),碘化钾(1.00g,0.006mol),100mL丙酮置于250mL茄形瓶中。搅拌,用10mL丙酮稀释苄基氯(7.87g,0.06mol),并以恒定速率滴入反应溶液中。添加在大约10分钟内完成。将反应加热回流6小时,通过TLC监测反应。反应完成后,冷却至室温,减压蒸馏除去有机溶剂,得到黄色晶体。用50mL乙醇重结晶,得到9.84g黄色晶体。条件:With potassium iodide In acetone for 6 h; Reflux收率:81.3%(重结晶后);总产率66%(中间体1-7)参考文献:[1] Journal of Chemical Research, Miniprint, 1981, # 7, p. 2564 - 2572 [2] Patent: CN107857748, 2018, A.
