Abstract We have achieved the first catalytic enantioselective synthesis of planar-chiral metacyclophanes by means of cationic Rh(I)/(S)-xyl-H8-BINAP or (R)-H8-BINAP complex-catalyzed inter- and intramol. alkyne cyclotrimerizations. This highly enantioselective catalysis represents a versatile new method for the prepn. of planar-chiral metacyclophanes. [on SciFinder(R)]
