摘要
The cationic gold(I)/(R)-xyl-binap complex was shown to catalyze the atroposelective intramolecular hydroarylation of alkynones to produce enantioenriched axially chiral all-benzenoid biaryls, 4-aryl-2-naphthol derivatives, with up to 67%ee. The reaction of a racemic alkynone in the presence of the same gold(I) catalyst also afforded the corresponding axially chiral all-benzenoid biaryl in excellent yield with 70%ee.
