Abstract

Chiral Ag-atropisomeric ligand species were studied in solution at different temperatures by 31 P-NMR spectroscopy. The analysis and understanding of key parameters in Ag-BINAP complexes were considered in the context of an enantioselective transformation. An efficient silver-catalyzed intramolecular [4+2] cycloaddition reaction of amide-1,6-enyne provided an enantiomerically enriched tricyclic compound using simple reagents and under mild reaction conditions.
