[摘要]：Cycloaddition and cycloisomerization based on the interaction between an allene and another multiple bond, such as an alkyne, alkene, or additional allene, enabled us to build a variety of useful cyclic structures. This account describes our research on allene cycloaddition and cycloisomerization, categorizing the reactions by the proper reaction mode and the cyclic framework of the product. 1 Introduction 2 Construction of Bicyclo[m.3.0] Skeletons via Carbonylative [2+2+1] Cycloaddition 2.1 From Allene-Ynes and Aza Analogues 2.2 From Allene-Enes 2.3 From Bis-allenes 3 Construction of Bicyclo[m.2.0] Skeletons via [2+2] Cycloaddition 3.1 From Allene-Ynes 3.2 From Bis-allenes 4 Construction of Bicyclo[4.4.0] Skeletons via 6 pi-Electrocyclization/[4+2] Cycloaddition 5 Construction of Monocyclic Polyenes via Cycloisomerization 5.1 From Allene-Ynes 5.2 From Allene-Enes 5.3 From Bis-allenes 6 Construction of Bicyclo[5.m.0] Skeletons via [5+2] Cycloaddition 7 Conclusions and Outlook |
