以6-喹啉羧酸甲酯为原料合成6-羟甲基喹啉的一般步骤:在-78℃的丙酮-干冰浴中冷却0.2M的6-喹啉羧酸甲酯(0.300g,1.60mmol)的THF(8mL)溶液和0.6M的二异丁基氢化铝(DIBAL)(0.860mL,4.81mmol)的THF溶液(8mL)。通过套管将DIBAL溶液转移至甲酯溶液中,所得溶液在0℃下搅拌1小时。反应通过在0℃下加入甲醇(8mL)和乙酸(1.37mL,24.0mmol)淬灭。搅拌5分钟后,加入饱和酒石酸钠溶液(16mL)。继续搅拌20分钟,随后用EtOAc(50mL)和水(10mL)稀释反应混合物。水层用EtOAc(3×50mL)萃取。合并有机相,用15mL水洗涤一次。有机层用Na2SO4干燥,过滤后减压浓缩。通过柱色谱(50-90%EtOAc/己烷)纯化,得到0.236g(93%)的6-羟甲基喹啉(S3a),为淡黄色油状物。1H NMR(500MHz,CDCl3):δ4.89(s,2H),7.35(dd,1H,J=4.0,8.0),7.65(dd,1H,J=1.5,9.0),7.77(s,1H),8.01(d,1H,J=9.0),8.08(d,1H,J=4.0),8.80(dd,1H,J=1.5,4.0)。13C-NMR(125MHz,CDCl3):δ64.8,121.5,125.0,128.3,129.0,129.4,136.4,139.9,147.7,150.2。HRMS-FAB(m/z):[MH]+ C10H10NO的计算值,160.0762;实测值:160.0766。
