Gold(I)-Catalyzed Addition of Silylacetylenes to Acylsilanes: Synthesis of Indanones by C-H Functionalization through a Gold(I) Carbenoid

A gold(I)-catalyzed synthesis of indanones from trimethylsilylacetylenes and acylsilanes is presented. The reaction is initiated through a synergistic acylsilane activation-gold acetylide formation and involves consecutive alkyne σ-gold(I) addition, π-activation, and 1,2-migration of a silyl group. Studies performed on the reaction mechanism allowed to establish the nature of the silyl migrating group and invoke the participation of a gold(I) carbenoid intermediate. The reaction is completed by a gold(I) C-H functionalization step.
Superacid-promoted dual C-C bond formation by Friedel-Crafts alkylation and acylation of ethyl cinnamates: Synthesis of indanones

A superacid (triflic acid) promoted dual C-C bond formation via intermolecular Friedel-Crafts alkylation (Michael addition type) and intramolecular acylation for the efficient synthesis of 3-substituted indan-1-ones is presented. This method was successful in activating ethyl cinnamates towards dual aromatic electrophilic substitution. Moreover, it enabled us to synthesize novel spirotetracyclic systems.
