摘要
Substituted maleic anhydrides function as synthetic equivalents of alkynes in a rhodium(III)-catalyzed reaction with 1,6-diynes to achieve a formal [2+2+2] cyclotrimerization. This approach is useful for reactions involving alkynes with low boiling points or severe ring strain. Hard-to-access [2+2+2] cycloadducts are available through this new cycloaddition strategy by employing easy-to-handle alkyne equivalents.
