[ZnI3]À signals were observed. Likewise, signals of [Zn(OTf)2OTs]À
and [Zn(OTf)3]À were identified in the mixture of Zn(OTf)2 and
TsOHÁH2O complexes, which provided direct support for the
associative interaction between the Lewis acid and Brønsted acid
(see the ESI†). (4) Zn(OTf)2 and TsOHÁH2O successfully catalyzed

yield (Scheme 3) whereas TfOH, which might be generated in situ
and acted as a hidden Brønsted acid catalyst,3g,7,8 was not able to
catalyze the same reaction based on Hartwig’s report.2j Another
direct cross-comparison with reported reactions was conducted
and is displayed in Fig. 2. The very electron deficient alkene 1w
did not react under the reaction conditions reported by Lebœuf2a
and Hartwig2j respectively. By applying the combined-acid strategy,
pyrrolidine 2w was obtained through intramolecular hydroamina-
tion for the first time in 91% yield, which corroborates the
advantages of the present catalyst system. The proposed process
of LBA catalysis demonstrates that the catalytic activity of the
Brønsted acid, TsOH or other protic acids generated in situ in these
transformations was dramatically increased by the presence of a
Lewis acid (Zn(II) salts).

for the syntheses of saturated heterocycles, tetrahydronaphthalene
derivatives and polycyclic compounds in an atom-economical
manner. Most of these reactions can be easily conducted
in screw-cap vials with stirring bars at room temperature. The
low-cost reagents and mild reaction conditions provide high
Markovnikov regioselectivity. The mechanism is thought to
involve designer acids (Lewis acid-assisted Brønsted acid) that
facilitate proton transfer.
