Regioselective synthesis of 3-aryl substituted pyrrolidines via palladium catalyzed arylation: pharmacological evaluation for central dopaminergic and serotonergic activity.
摘要:
A series of 3-arylpyrrolidines has been synthesised via palladium catalyzed arylation and evaluated for dopaminergic and serotonergic activity in vitro and in vivo. Compounds substituted by electron withdrawing groups on the meta position of the aromatic ring, were found to be preferential dopamine autoreceptor antagonists. (C) 1997, Elsevier Science Ltd.
additive excluded the use of silver and thallium salts, but high regioselectivity and good yields could be obtained by employing tri-2-furylphosphine as ligand. Arylation was rendered both regioselective and enantioselective (58% ee) with 1-naphthyl triflate as substrate utilizing a (R)-BINAP/thallium acetate combination. The C-3 arylated enamides were converted further into the corresponding 3-arylpyrrolidines
