本发明在下面的实施例中进一步加以说明,但不能认为受这些实施例的限制。
实施例1
酰化的8-羟基-3-甲基喹啉的制备
将8-羟基-3-甲基喹啉盐酸盐(200g,1.02mol)和氢氧化钠(102g,2.55mol)在1000ml水中的混合物用乙酐(208g,2.04mol)0-10℃处理1小时以上,室温搅拌1小时。再加入部分乙酐(50g,0.49mol),所得混合物再搅拌1小时。滴加饱和碳酸氢钠(100ml)。滤集粗产物,水洗,60℃真空干燥,从乙酸乙酯和庚烷中重结晶,得白色针状体(168.5g,得率82%)。
将8-羟基-3-甲基喹啉盐酸盐(10g,0.051mol)和三乙胺(15.5g,0.15mol)在100ml二氯甲烷中的混合物用苯甲酰氯(10.8g,0.077mol)0-10℃处理1小时以上,室温搅拌3小时。加水,有机相用水洗三次,用硫酸镁干燥。蒸发,从庚烷/甲苯中重结晶,得产物淡黄色结晶(8.8g,得率65%)。
同样制得其它酰化的8-羟基-3-甲基喹啉。
实施例2
将8-乙酸基-3-甲基喹啉(168.5g,0.84mol)、N-溴丁二酰亚胺(NBS)(177.9g,1.00mol)和2,2′-偶氮二异丁腈(AIBN)(6.7g,0.004mol)在1675ml氯苯中的溶液用氮气吹扫,在氮气下80-90℃加热2小时,冷却至室温并过滤。滤液与丙酮(700ml)混合,并用三甲胺(75.4mg,1.28ml)0-5℃处理,5-10℃搅拌30分钟,然后室温搅拌1小时,过滤。滤饼用丙酮洗涤,60℃真空干燥,得白色固体(180g,总收率63%)。获得的最高收率为77%。
其它酰化的8-乙酸基-3-甲基喹啉以相似的收率得到相应的季盐。
季盐制备的条件变异和关键因素
(1)氯苯是推荐的溶剂。
(2)浓度可低至0.2g乙酸酯/10ml溶剂,或高至1g乙酸酯/10ml溶剂。它可更加浓缩,只要所有的反应剂在反应温度下均溶解。
(3)温度通常限制在80-95℃。温度低于此范围时反应缓慢,高于此范围时出现副反应。
(4)AIBN的量可为2%-10%。
(5)与三甲胺的反应通常在-10-10℃进行。
(6)母体化合物8-羟基-3-甲基喹啉抑制溴化作用,因而其含量应限制在5%以下。
(7)溴化作用在氮气氛围下进行。氧气可阻滞该反应。
实施例3
8-羟基-3-甲氧基甲基喹啉
将溴化(8-乙酸基喹啉-3-基)甲基三甲铵(80g,0.24mol)的15%甲醇钠甲醇液(250g,0.69mol)在加压反应器中120℃加热18小时,减压浓缩。残渣用水稀释,将pH调至7-8,过滤。滤饼用水洗,60℃真空干燥,得一棕黄色固体(收率91%)。
实施例4-17阐述采用不同条件的甲氧基化反应。将溴化季铵的甲醇溶液和3当量碱,可任选一催化剂,在密封的反应器中65-180℃加热16-96小时,减压浓缩。残渣用水稀释,pH调至7-8,过滤。滤饼用水洗涤,60℃真空干燥,得棕黄色固体产物。实施例 条 件 时间(小时) 收率4 无催化剂, NaOMe, 65℃ 31 4%5 无催化剂, LiOMe, 65℃ 31 50%6 5%CuSO4, NaOMe, 65℃ 31 65%7 10%CuSO4, NaOMe, 65℃ 22 94%8 10%CuSO4, K2CO3, 65℃ 96 73%9 50%CuSO4, K2CO3, 65℃ 47 98%10 5%FeSO4, K2CO3, 65℃ 96 67%11 10%ZnCl2, NaOMe, 65℃ 20 38%12 1-2%CuSO4,K2CO3, 150℃ 22 69-91%13 1-2%CuSO4,NaOMe, 120℃ 17-21 ~80%14 无催化剂, 13%NaOMe, 120℃ 19 73%15 无催化剂, 15%NaOMe, 120℃ 18 74%16 无催化剂, NaOMe, 150℃ 17 73%17 无催化剂, NaOMe, 180℃ 16 69%18 无催化剂, K2CO3, 150℃ 16.5 65%
当式IV的X=Ph时,季盐和碳酸钾在甲醇中150℃加热18小时后,得到粗收率82%的终产物。
当式IV的X=OMe时,季盐和碳酸钾在10%CuSO4存在下,在回流甲醇中加热22小时,得到粗收率90%的终产物。
甲氧基化的条件变异和关键因素
(1)过渡金属例如,但不限于,CuSO4、FeSO4、ZnSO4、ZnCl2催化此反应。
(2)反应温度可在65℃-180℃间变化。更高的温度可引起副反应,更低的温度则反应可能非常缓慢。
(3)甲醇是较佳的溶剂。二甘醇二甲醚或DMSO,和NaOMe一起,也可用作溶剂。
(4)甲醇钠和碳酸钾对于反应是最佳的,虽然其它碱,如Li- OMe、KOMe、Ca(OMe)2、Mg(OMe)2、NaHCO3、Na2CO3、KHCO3、CaCO3、Me3N、Et3N和吡啶可在适当的条件,如较高的温度下使用。事实上,反应可不加碱而进行,因为在反应过程中产生碱(Me3N)。
(5)浓度不是关键性的。所采用的最高浓度是15%NaOMe,或3g季盐/10ml甲醇,最低浓度是0.2g季盐/10ml甲醇。
