one-pot aminoalkoxylation of styrenes using primary and secondary alcohols and three different iminoiodanes as alkoxy and nitrogen sources respectively, is reported. The β-alkoxy-N-protected phenethylamines obtained were used to synthesise β-alkoxy-N-benzylphenethylamines which are interesting new compounds that could act as possible neuronal ligands.

A practical approach for the synthesis of 3-substituted indolines via regio- and stereoselective S(N)2-type ring opening of 2-(2-halophenyl)-N-tosylaziridines with heteroatomic nucleophiles (O, N, and S) followed by palladium catalyzed intramolecular C-N cyclization is reported in excellent yields (up to >99%) and enantiomeric excess (ee 99%)
