A tandem dehydrative cyclization/aza-hetero-Diels–Alder reaction catalyzed by gold(I)
complex bearing BINOL-derived chiral phosphoramidite ligand has been developed. With
this method, optically active chiral bicyclic tetrahydropyridazine derivatives could
be obtained in one step from readily available starting materials.
Key words
asymmetric gold catalysis - tandem reaction - hetero-Diels–Alder reaction
