Description
技术领域
本发明属于化学合成技术领域,特别涉及一种制备含咔唑基查尔酮的方法及产品。
背景技术
现有制备咔唑基查尔酮的方法一般是用乙酰基咔唑与相应的醛类发生Knoevenagel缩合反应生成咔唑基查尔酮,其反应式如下所示:
用以上方法制备咔唑基查尔酮时,首先需要制备3-乙酰基-9-取代基咔唑,而由于N-取代基咔唑结构的对称性,进行Friedel-Crafts反应生成3-乙酰基-9-取代基咔唑的同时会生成3,6-二乙酰基-9-取代基咔唑,所以要制备高纯度的3-乙酰基-9-取代基咔唑操作较为繁琐,不宜提纯。然而3-乙酰基-9-取代基咔唑的纯度决定了发生Knoevenagel缩合反应生成咔唑基查尔酮的纯度。
发明内容
本发明的目的是提供一种制备含咔唑基查尔酮的方法,该方法能高产率、高纯度的制备含咔唑基查尔酮。
为了实现上述目的,本发明采用如下技术方案:
一种含咔唑基查尔酮的制备方法,其包括以下步骤:
第一步,向反应容器中加入配方量的取代丙烯酸(A)和五氯化磷(B),于室温搅拌反应30min;
第二步,将反应体系冷却至0℃后,加入配方量的N-取代基咔唑(C)溶液和Lewis酸(D),缓慢升温至回流温度,TLC监测至反应结束;
第三步,向反应体系中加入适量的水,搅拌均匀后静置分液,有机相用饱和碳酸钠洗涤,蒸干溶剂,得到粗品;
第四步,粗品用无水乙醇重结晶得到纯品。
所述取代丙烯酸的结构式为:
或者,
或者,
或者,
其中,Z=S;O;R=o-CH3;m-CH3;p-CH3;o-OCH3;m-OCH3;p-OCH3;o-NO2;m-NO2;p-NO2;o-F;m-F;p-F;o-Cl;m-Cl;p-Cl;o-Br;m-Br;p-Br;o-CN;m-CN;p-CN;o-OH;m-OH;p-OH;o-CH(CH3)2;m-CH(CH3)2;p-CH(CH3)2;2,3-2-Cl;2,4-2-Cl;2,3-2-Br;2,4-2-Br;2,3-2-F;2,4-2-F;4-Br-2-NO2;2-OH-3-NO2;
所述N-取代基咔唑结构式为:
其中,R1=Me;Et;CH2Ph;C12H25-n;C14H29-n;C16H32-n;Ph;
所述步骤中,取代丙烯酸:五氯化磷:N-取代基咔唑:Lewis酸的摩尔比为1:(1~2):(1.1~1.2):(1.2~1.5)。
所述第二步中N-取代基咔唑溶液的溶剂为二硫化碳、二氯甲烷、氯仿或1,2-二氯乙烷中的一种。
将N-取代基咔唑溶解于溶剂量的上述溶剂中,配制成N-取代基咔唑溶液。
所述Lewis酸为无水氯化锌、无水氯化铝、三氟化硼或无水氯化铁中的一种。
本发明反应机理:通过取代丙烯酸和五氯化磷反应得到取代丙烯酰氯,再在Lewis酸催化下,与N-取代基咔唑发生Friedel-Crafts反应制备咔唑基查尔酮。
本发明还公开了一种含咔唑基查尔酮类化合物,所述化合物的结构式为:
或者,
或者,
或者,
其中,Z=S;O;R=o-CH3;m-CH3;p-CH3;o-OCH3;m-OCH3;p-OCH3;o-NO2;m-NO2;p-NO2;o-F;m-F;p-F;o-Cl;m-Cl;p-Cl;o-Br;m-Br;p-Br;o-CN;m-CN;p-CN;o-OH;m-OH;p-OH;o-CH(CH3)2;m-CH(CH3)2;p-CH(CH3)2;2,3-2-Cl;2,4-2-Cl;2,3-2-Br;2,4-2-Br;2,3-2-F;2,4-2-F;4-Br-2-NO2;2-OH-3-NO2;R1=Me;Et;CH2Ph;C12H25-n;C14H29-n;C16H32-n;Ph
与现有技术相比,本发明具有以下优点:
第一:通过“一锅法”进行咔唑基查尔酮的制备,减少了中间处理步骤,简便了实验操作,节省原料;
第二:含有Lewis酸催化剂的废水可经去除有机物后,再多效蒸发浓缩后,用作制备净水剂;
第三:通过本发明的方法能高效率、高产率、高纯度的制备咔唑基查尔酮。
具体实施方式
本发明一种含咔唑基查尔酮的制备方法,首先取代丙烯酸和五氯化磷反应生成取代丙烯酰氯,然后再在反应器中加入1,2-二氯乙烷、Lewis酸(AlCl3)和N-取代基咔唑,发生Friedel-Crafts反应制备咔唑基查尔酮,其反应式如下:
下面结合本发明的具体实例对本发明作进一步详细说明,但本发明的实施方式不限于此。
实施例1 1-(3-N-甲基-咔唑基)-3-苯基-丙烯酮(1)的制备:
第一步,向反应容器中加入0.05mol肉桂酸和0.075mol五氯化磷,于室温搅拌反应30min;
第二步,将反应体系冷却至0℃后,搅拌下滴入0.06mol N-甲基咔唑和25mL1,2-二氯乙烷的混合溶液、0.06mol AlCl3缓慢升温至回流温度,TLC监测至反应结束;
