Using Zn(OTf)2 as catalyst, a highly regio- and chemo-selective cyclocarboamination of o-alkynylbenzaldehydes with tertiaryalkylprimaryamines was realized to access 3-aminoindenes with different substitution patterns from previously reported methods. The full reduction of the iminoindenone intermediates affords cis-1-amino-2-arylindanes with excellent diastereoselectivity. Mechanistically, the reaction
