The preparation of new chiral biphenylic λ -iodane reagents bearing transferable alkynyl ligands is described. These reagents transfer their carbon-based ligands onto β-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.
本文描述了带有可转移炔基配体的新型手性联苯型λ-碘烷试剂的制备。这些试剂能将其基于碳的配体转移到β-酮酯上，对映体过量（ee）高达68%，最值得注意的是，能以良好至高收率实现萘酚的去芳构化炔基化反应，对映体过量高达84%。
