A class of (S)-H8-BINOL-derived chiral η6-benzene ligands has been developed, which can coordinate with ruthenium(II) highly site-selectively.The related chiralruthenium(II) catalysts proved highly effective for the asymmetric C−H activation of N-sulfonyl ketimines with alkynes, affording a series of chiral spirocyclic sultams in up to 99 % yield with up to >99 % ee.
