Abstract

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.
