In(III)/PhCO2H Binary Acid Catalyzed Tandem [2 + 2] Cycloaddition and Nazarov Reaction between Alkynes and Acetals
摘要:
A facile tandem [2 + 2] cycloaddition and Nazarov reaction has been developed. The combination of In(OTf)(3) and benzoic acid was found to synergistically promote the coupling of alkynes and acetals to form 2,3-disubstituted indanones in excellent yield and diastereoselectivity.

An efficient intramolecular palladium-catalyzed, asymmetric reductive-Heck reaction has been developed, which allowed for the synthesis of either enantiomericallyenriched 3-substituted indanones or α-exo-methylene indanones depending on the base used.

Asymmetric reductive Heck reaction of arylhalides is realized in high stereoselectivity. Hydrogen‐bond donors, trialkylammonium salts in a glycol solvent, were used to promote halide dissociation from neutral arylpalladium complexes to access cationic, stereoselective pathways.
