过渡金属催化炔烃环化反应的研究进展

Recent advances on transition-metal-catalyzed cyclization of alkynes

具有独特反应性和稳定性的炔烃类化合物一直以来是科研工作者们关注的热点之一,其中关于炔烃环化构筑一系列多环化合物的反应报道尤为突出。本文根据不同金属催化剂,总结归纳了近几年铑、钌、钴、钯等过渡金属催化炔烃环化反应的研究进展,并简要讨论了催化转化的反应机理、优势以及局限性,最后展望了过渡金属催化炔烃环化反应的发展前景。

With the especial reactivity and stability,the alkynes had been one of the research hotspots for constructing a series of polycyclic compounds.In this review,the up-to-date summaries of transition-metal-catalyzed cyclization of alkynes on the basis of metal catalysts such as rhodium,ruthenium,cobalt and palladium were gave.It was pointed out that the plausible mechanisms,advantages and limitations in these transformations.Finally,the outlooks for transition-metal-catalyzed cyclization of alkynes was suggested.
