Diastereoselective tricyclization/dimerization of yne-indoles catalyzed by a Au(III) complex featuring an L2/Z-type ligand
Abstract
Abstract In order to investigate catalyst activation via a (Au\xa0→\xa0B)8 interaction, Au(DPB)X3 (DPB\xa0=\xa0diphosphine-borane) featuring an L2/Z ligand was synthesized. The resulting cationic catalyst was utilized for the unprecedented diastereoselective tricyclization/dimerization of yne-indoles.
