Copper-catalyzed intermolecular formal [4 + 1] annulation of 1,5-diynes with benzocyclobutenones
The one-carbon ring expansion of benzocyclobutenones is an efficient methodology for the assembly of cyclic ketones. However, hazardous reagents or noble metal catalysts are frequently required. Herein, we disclose a copper-catalyzed intermolecular formal [4 + 1] annulation of 1,5-diynes with benzoc...
