A series of N-substituted 7-azabicyclo[2.2.1]heptanes (12–17 and 22–25) and similarly substituted pyrrolidines (32–36 and 41–44) were synthesized as sterically-reduced, achiral analogs of adamantane- and trishomocubane-derived σ ligands. In vitro competition binding assays against σ receptors revealed that arylalkyl N-substituents conferred selectivity for the σ2 subtype, while alicyclic or polycarbocyclic

dianion; pyr is the pyrrolidine) catalyze the addition of pyrrolidine to 2-vinylpyridine at room temperature. The compound (dppbian)Mg[N(SiMe3)2] containing a dpp-bian radical anion catalyzes the addition of pyrrolidine to styrene at 60 °C. The dpp-bian radical anion lithium-sodium salt [(dpp-bian)LiN-(SiMe3)2}][Na(C7H8)] is an active catalyst of the addition of pyrrolidine to styrene and isoprene
rhodium complexes catalyze the amination of 2- and 4-vinylpyridine with secondary amines. Depending on the substrate and the reaction conditions either oxidative amination to yield the corresponding enamines 1a–8a or hydroamination to give 2-aminoethylpyridines 1b–8b occurs. In all cases products with anti-Markovnikov regioselectivity are obtained. For mechanistic studies novel cationic complexes of r

yields using the Aza-Michael-type addition of various amines to vinyl compounds catalysed by a supported ionic liquid incorporating an anionic heteropoly acid. Different catalysts, including Lewisacids, Brønsted acids and heteropoly acids were investigated in which heteropoly acids having dual Brønsted and Lewisacid characteristics were excellent catalysts. The ionic liquid incorporating a polytungstate
