摘 要烯基叠氮化合物,是碳碳双键C=C和叠氮官能团直接相连的一类官能化烯烃,是构筑碳-碳单键C-C和碳-氮键C-N最有效的合成中间体之一。1910年,Forster等化学家以2-氯乙醇和叠氮化钠为原料,成为人类合成烯基叠氮母体结构的第一例。但是,由于操作过程繁琐、产率低、产物不稳定易爆炸等缺陷,在随后的近五十年内很少有烯基叠氮化合物的研究成果。直至二十世纪六十年代,以Hemetsberger-Knittel合成法和Hassner的叠氮化卤和烯烃通过加成-消除反应来制备的方法为首的,多种新型、高效的合成烯基叠氮类化合物的方法相继被报道,关于烯基叠氮的研究再一次地引起了全世界化学家的广泛关注和浓厚兴趣。89000
随着研究者们对烯基叠氮应用的探索,越来越多的研究证明,金属催化烯基叠氮化合物在合成含氮杂环化合物的反应中发挥了特有的优势。而不同金属条件下烯基叠氮的反应性能的高低,引起了人们的极大兴趣,迅速成为有机化学研究发展的热门领域。针对以上问题,我开展了相应的研究工作,取得了系列研究成果。
Vinyl azide compounds, are one kind of function olefins which containin carboncarbon double bond and azide unit。 In 1910, chemists like Forster, used ethylene chlorohydrin and sodium azide as raw materials in marking the matrix of vinyl azide。 This is the first instance of vinyl azide synthesis。 However, because of the weak points, such as the complicated process, low productivity, the inflammable unsteady products and so on, in the following nearly fifty years, there were very few research findings on vinyl azide compounds。 Up to the 1960s, giving priority to Hemetsberger-Knittel indole synthesis and Hassner’s synthesis ways based on halogen azides and olefins through addition-elimination reaction, a lot of new and efficient ways in making vinyl azide compounds were reported one after another。 It did give rise to wide concerns and strong interests in the whole chemistry community worldwide。SSS
Along with researchers’ explorations about the applications of vinyl azides, an ever increasing number of studies proved that metal catalysts play a unique advantage in applications of vinyl azides to obtain nitrogen heterocycles。 At this time, the natural reactivity of vinyl azides with different metal catalysis has attracted great interests, and quickly becomes a hot area in organic chemistry research。 To solve these sticky problems, I have carried out the corresponding research work and then obtained series of good results。
