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.
