This project focused on the development of new reactions of highly strained alkynes such as arynes and heteroarynes using a transition metal catalyst. A novel method for construction of biaryls via palladium-catalyzed [2+2+2] cocyclization of diynes and arynes was developed. By this methodology, various arylnaphthalene derivatives, including a sterically hindered 2,2'-disubstituted-1,1'-binaphthyl, can be constructed by virtue of a variety of combinations of diynes and aryne precursors. Using this reaction as a key step, the total syntheses of taiwanins C, E, and dehydrodesoxypodophyllotoxin were achieved. Furthermore, a [2+2+2] cocyclization of diynes and heteroarynes was also investigated. As the result, a nickel-catalyzed [2+2+2] cocyclization of diynes and 3,4-pyridynes was developed for the first time, affording isoquinoline derivatives in good yields. In this reaction, an electron-donating substituent on the pyridine ring of the 3,4-pyridyne precursor was tolerated, giving various substituted isoquinolines in good yields, respectively. On the other hand, it was found that an electron-withdrawing substituent on the pyridine ring of the precursor retarded the [2+2+2] cocyclization.

该项目的重点是使用过渡金属催化剂开发高张力炔烃（例如芳炔和杂芳烃）的新反应。开发了一种通过钯催化二炔和芳炔的[2+2+2]共环化构建联芳基的新方法。通过这种方法，各种芳基萘衍生物，包括空间位阻的2,2'-二取代-1,1'-联萘，可以通过二炔和芳炔前体的各种组合来构建。以此反应为关键步骤，实现了台湾毒素C、E和脱氢鬼臼毒素的全合成。此外，还研究了二炔和杂芳烃的[2+2+2]共环化。结果，首次开发了镍催化的二炔和3,4-吡啶的[2+2+2]共环化反应，以良好的产率提供了异​​喹啉衍生物。在此反应中，3,4-吡啶前体的吡啶环上的给电子取代基是可以耐受的，分别以良好的产率得到各种取代的异喹啉。另一方面，发现前体吡啶环上的吸电子取代基阻碍了[2+2+2]共环化。
