摘要：

[GRAPHIC] Arylboronate esters bearing a pendant Michael-acceptor alkene can add to norbornene and cyclize to give indane systems in yields ranging from 62% to 95% with high diastereomeric excess (>20:1). The reaction is performed in an organic/aqueous emulsion and catalyzed using [Rh(COD)Cl](2) with t-Bu-amphos chloride, a sterically bulky, electron-rich, water-soluble phosphine ligand.
