A General Synthesis of Ynones from Aldehydes via Oxidative C–C bond Cleavage under Aerobic Conditions

Zhaofeng Wang, Li Li and Yong Huang*, J. Am. Chem. Soc. 2014, 136, 12233–12236

We describe a direct synthesis of various ynones from readily available aldehydes and hypervalent alkynyl iodides. In this method, a gold catalyst and a secondary amine work synergistically to produce the trisubstituted allenyl aldehyde, which can be converted to the desired ynone through an in situ C–C bond oxidative cleavage using molecular oxygen.
