Syntheses of tetrahydroquinoline-based chiral carbene precursors and the related chiral NHC–Au(i) complex

摘要

Four tetrahydroquinoline-based chiral carbene precursors were synthesized using unsymmetrical N , N ′-diarylformamidines and chiral 2-allyloxiranes as starting materials. A representative NHC–gold complex has been prepared and fully characterized, the crystal structure of which reveals an intramolecular Au?H–C(sp ~(3) ) interaction between Au( I ) and the hydrogen atom of the isopropyl moiety in the N -aryl group.
