Gold-Catalyzed Regioselective Oxyfluorination/Oxydifluorination vs. Diketonization of Phthalimido-Protected Propargylamines with Selectfluor

, (2022/01/22)
Alkyl- and aryl-substituted N-propargyl phthalimides were used as valuable building blocks for the selective formation of the corresponding α-fluoro, β-phthalimido ketones, α,α-difluoro, β-phthalimido ketones or β-phthalimido α-diketones by means of gold-catalyzed oxyfluorination/oxydifluorination or dioxygenation reactions. The key factors addressing the product selectivity control were determined. The simultaneous assembly of the quinoxaline nucleus and the removal of the phthalimido-protecting group were tested. Reaction mechanisms of the different reaction pathways are assumed.

The Au(i)-catalyzed intermolecular hydroalkoxylation of alkynes with allylic alcohols to provide allyl vinyl ethers that subsequently undergo Claisen rearrangement is reported. This new cascade reaction strategy facilitates the direct formation of γ,δ-unsaturated ketones from simple starting materials in a single step.
