Description

1,4-二醛酮化合物、其合成方法及应用
技术领域
本申请具体涉及一种1,4-二醛酮化合物、其合成方法及应用,属于有机化学技术领域。
背景技术
1,4-酮醛是许多天然产物和药物化合物的常见亚结构,也是构建生物学上重要的异环化合物的通用构建块。许多努力都致力于发展新的合成方法。然而,由于酮碳基单元和醛单元在1,4-关系中的结合通常需要一个碳基底物的极性反转。迄今为止,能高效和通用合成1,4-酮醛的方法尚较少被报道。已知的主要方法包括:烯丙醇的有机催化异构化;铜催化烯胺酮衍生的环丙烷中间体的键裂解;在烷基乙烯酮中插入α-溴自由基;磺胺[3,3]重排等。通过逆合成分析,1,4-醛酮拆分为两个羰基部分的电性不匹配,难以偶联。
发明内容
本发明的主要目的在于提供一种1,4-二醛酮化合物及其合成方法和应用,该合成方法利用极性反转策略实现醛羰基与酮羰基的电性匹配偶联来制备1,4-醛酮化合物,从而克服现有技术的不足。
为实现上述发明目的,本发明采用了如下技术方案:
本发明的一个方面提供了一种1,4-醛酮化合物,其具有下式所示结构:
其中Ra包括H、卤素、取代或未取代的烷基、取代或未取代的芳基、取代或未取代的杂环基、取代或未取代的烯基、炔基、酯基、氨基或氰基,Rb包括H、卤素、取代或未取代的烷基、取代或未取代的芳基或者取代或未取代的杂环基。
在一个实施例中,所述1,4-醛酮化合物包括下列的任一种化合物:
本发明的另一个方面提供了一种1,4-醛酮化合物的合成方法,其包括:使包含脂肪醛,烯氧基吡啶鎓盐和二级胺的均匀混合反应体系于室温下进行反应,获得1,4-醛酮类化合物。
在一个实施例中,所述的二级胺包括二乙胺、吡咯、吗啉、N,N-二异丙基乙胺、N-甲基苯基胺中的任意一种或多种的组合,且不限于此。
在一个实施例中,所述脂肪醛具有式(I)所示结构:
其中,Rb包括H、卤素、取代或未取代的烷基、取代或未取代的芳基或者取代或未取代的杂环基。
示例性的,所述脂肪醛包括苯丙醛、对氯苯丙醛、对溴苯丙醛、噻吩-2-丙醛、5-甲基呋喃-2-丙醛、2-环己基-1-乙醛、正丁醛、正己醛、正庚醛、正壬醛、6-氯-1-己醛等,但不限于此。
在一个实施例中,所述烯氧基吡啶鎓盐具有式(II)所示结构:
其中,Ra包括H、卤素、取代或未取代的烷基、取代或未取代的芳基、取代或未取代的杂环基、取代或未取代的烯基、炔基、酯基、氨基或氰基,X-包括负电性基团。
在一个实施例中,X-包括-NTf2
在一个实施例中,所述脂肪醛与烯氧基吡啶鎓盐的摩尔比为0.8∶1-1∶0.8,所述二级胺与脂肪醛的摩尔比为0.8∶1-1∶0.8。
在一个实施例中,所述反应的时间为0.5h以上。
在一个实施例中,所述均匀混合反应体系还包括有机溶剂。进一步的,所述有机溶剂包括二氯甲烷、二氯乙烷、乙腈、甲醇、N,N-二甲基甲酰胺、甲苯中的任意一种或多种的组合,且不限于此。
本发明的另一个方面还提供了所述1,4-醛酮化合物在合成碳环化合物或杂环化合物中的用途。所述碳环化合物或杂环化合物可以用于制备药物,例如抗肿瘤药物。
较之现有技术,本发明提供了一种由脂肪醛直接制备1,4-醛酮化合物的方法,该方法是利用一锅法在二级胺的催化下使得二级胺与脂肪醛快速生成烯胺化合物,烯氧基吡啶鎓盐本身是高活性的亲电试剂,容易与烯胺中的双键进行反应,得到反应中间体后,在本身反应体系中水的进攻下中间体中的亚胺正离子水解成醛基,可以实现1,4-醛酮化合物的制备,该合成工艺简洁高效,制得的1,4-醛酮化合物可以用于制备抗肿瘤药物或药物中间体等,在医药等领域的应用前景广阔。
附图说明
图1a-图1c分别示出了本申请实施例中化合物5对人卵巢癌细胞(SKOV3)、人乳腺癌细胞(MCF-7)和人肝癌细胞(HepG2)的增殖活性的抑制效果。
具体实施方式
鉴于现有技术中的不足,本案发明人经长期研究和大量实践,得以提出本发明的技术方案,其利用二级胺催化脂肪醛化合物,很容易的生成了稳定烯胺中间体,这一方式远远优于现有技术中需要在甲苯中110℃反应较长时间才能得到烯胺化合物的方式,因烯胺结构中的双键具有一定的亲核性,而在烯氧基吡啶鎓盐的结构中具有强亲电性的双键不饱和基团,即烯氧基吡啶鎓盐本身是高活性的亲电试剂,通过使烯氧基吡啶鎓盐与烯胺结构中的双键进行反应,得到反应中间体后,在反应体系中水的进攻下,反应中间体中的亚胺正离子水解成醛基,可以实现1,4-醛酮化合物的制备,构建sp3-sp3杂化的碳碳键。
在一个较为典型的实施案例中,一种1,4-醛酮化合物的合成工艺原理可以参阅下式:
其中Ra、Rb可以选用前文所述的各种取代基团。
下面结合若干优选实施例对本发明的技术方案做进一步详细说明,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。
在如下实施例中,所有试剂和溶剂均从商业来源购买,使用时未经进一步净化,除非另有说明。所有反应均采用薄层色谱法(TLC)进行监测。除非另有说明,所有反应均在空气中进行。在硅胶(200-300目)上进行柱层析,用紫外线观察。用乙酸乙酯和石油醚作为洗脱剂。在室温下,以MDB为内标,CDCl3为溶剂,在JEOL ECZ400上记录1H、13C和19F光谱。多重性缩写为:s,单峰;d,双峰;t,三重峰;q,四重峰;se-Pt七重奏;m,多重峰;傅立叶变换红外光谱(FT-IR)在Agilent Technologies Cary 630仪器上记录。HRMS分析采用ESI-TOF方法。熔点在微熔点仪上测定。
在如下实施例中所使用到的一些原料的合成方法具体如下。
