Description
技术领域
本发明属于医药化工技术领域。更具体地,涉及2,3’-双呋喃类化合物和2,3’-低聚呋喃类化合物及其制备方法和应用。
背景技术
杂环化合物是有机化合物的重要组成部分,在许多天然产物中广泛存在,其具有独特的生物、生理及药理等活性。市场上超过90%的药物都至少含有一个杂环结构片段,而含氧杂环化合物是所有杂环化合物中最重要的化合物之一。
呋喃是一类非常重要的含氧杂环化合物。作为关键的结构单元,呋喃广泛存在于具有生物活性的天然产物中。每年都有大量的含有呋喃的天然产物被分离出来。呋喃及其衍生物已经成为天然产物化学一个重要的组成部分。在这些天然产物中,有很多都具有多样的生物活性。呋喃还是一类非常重要的合成中间体,被广泛用于有机合成中。例如海绵中提取的5-乙酰氧基甲基-2-呋喃甲酸、被细菌感染的桑树根的表皮和韧皮组织中分离出的桑素及人工合成的呋喃妥因等都具有抗菌活性;从花椒中提取出的化合物ailanthoidol具有抗病毒等活性。
此外,呋喃及其衍生物还可进一步衍生得到低聚呋喃化合物,如a)1981年,Kaufmann小组利用乌尔曼反应合成了一系列的2,2’-低聚呋喃;b)2014年,MichaelBendikov小组利用类似方法合成了多达16个重复单元的2,2’-低聚呋喃并对其进行氧化还原态的实验和计算研究;c)2012年,Michael S.Sherburn小组报导了第一例3,3’-低聚呋喃。目前低聚呋喃类化合物大多用于光学领域研究,但是其单体均是对称结构,而由非对称单体2,3’-双呋喃组成的2,3’-低聚呋喃的合成研究尚少有报道。
综上2,3’-双呋喃类化合物和2,3’-低聚呋喃类化合物及其制备是一个有价值的和具有挑战性的课题。
发明内容
本发明要解决的技术问题是克服现有技术的缺陷和不足,提供一种2,3’-双呋喃类化合物和2,3’-低聚呋喃类化合物。2,3’-双呋喃类化合物可用于生物活性研究和合成砌块,还可作为有光学应用前景的2,3’-低聚呋喃类化合物的合成单体,具有潜在工业化应用价值。
本发明另一目的是提供一种2,3’-双呋喃类化合物的制备方法。
本发明另一目的是提供一种2,3’-双呋喃类化合物的应用。
本发明另一目的是提供一种2,3’-低聚呋喃类化合物。
