title: Hf(OTf)4-catalyzed regioselective n-aminomethylation of indoles and related NH-containing heterocycles.
abstract: Under Lewis acidic conditions using Hf(OTf)(4), the aminomethylation of an indole derivative with a typical N,O-acetal preferentially produced kinetically favored N-aminomethylated indole derivatives instead of thermodynamically favored 3-aminomethylated indoles.
