ABSTRACT
The preparation of new chiral biphenylic λ3 -iodane reagents bearing transferable alkynyl ligands is described. These reagents transfer their carbon-based ligands onto ß-ketoesters with an enantiomeric excess (ee) up to 68 %, and most remarkably, enable the dearomative alkynylation of naphthols in good to high yields up to 84 % ee.
