一种手性γ-丁内酯类化合物及其衍生物的制备方法及其 应用
技术领域
本发明属于医药化合物合成领域,涉及一种手性γ-丁内酯类化合物及其衍生物的制备方法及其应用。
背景技术
γ-丁内酯骨架广泛存在于各种天然产物中,有重要的生物活性,如抗炎、抗癌和抗病毒等。基于呋喃酮的Michael加成反应是构建γ-丁内酯类化合物常用的方法之一。近年来,有机小分子催化的不对称反应以其反应条件温和、立体选择性高和易回收等优点受到高度重视。基于此,我们开展了基于呋喃酮骨架构建手性γ-丁内酯类化合物的有机小分子催化不对称反应研究。多官能团的γ-丁内酯化合物是合成一系列天然产物的重要中间体。因此,构建多手性中心、多官能团的γ-丁内酯类化合物一直是有机合成研究的热点。
2(5H)-呋喃酮是最简单的α,β-不饱和丁内酯,通过对其修饰,可以合成一系列不同取代的2(5H)-呋喃酮,而使用亲核试剂进攻2(5H)-呋喃酮或其衍生物可以合成各种取代的γ-丁内酯类化合物,是合成γ-丁内酯类化合物最常见的方法。
此外,由于醛的结构特点,在羰基中的π键极化,使得氧原子上带部分负电荷,而碳原子上带部分正电荷。反应中,分子中的碳氧双键很容易被亲核试剂进攻,并发生反应。并且受羰基的影响导致与羰基直接相连的碳原子上的氢很活泼,能发生一系列反应。
然而,目前没有报道称可以将醛与2(5H)-呋喃酮进行不对称地迈克尔加成以合成手性γ-丁内酯,简单、快速有效地构建多手性中心的方法,并且手性γ-丁内酯化合物对于环境条件要求严格,容易进行消旋化,从而使化合物构型改变。本发明则克服上述问题,开发了一种手性γ-丁内酯类化合物及制备方法并研究了改化合物的细胞活性。
