enantiomers with 1R,3S absolute configuration. 1S,3R enantiomers inhibited the uptake of dopamine and norepinephrine in vitro. The compound with the best antihypertensive activity was (+)-(1R,3S)-1-[2-[4-[3-(4-fluorophenyl)-1-indanyl]-1- piperazinyl]ethyl]-2-imidazolidinone (Lu 21-098, irindalone). Its pharmacological profile resembled that of the standard compound ketanserin. There was a close structural

The purpose of the present invention is to provide an N,N-bis(2-dialkylphosphinoethyl)amine-borane complex which is a ruthenium complex that exhibits excellent catalytic activity in a hydrogenation reaction, etc., and a production method therefor, and a method for efficiently producing a ruthenium complex containing N,N-bis(2-dialkylphosphinoethyl)amine as a ligand. The present invention is capable of efficiently producing an amine-borane complex (3) by reacting an oxazolidinone compound (1) with a dialkylphosphine-borane compound (2) in the presence of a base. The present invention is also capable of efficiently producing a ruthenium complex (5) by reacting the amine-borane complex (3) with a ruthenium compound (4) in the presence of an amine.

A highly selective hydrogenation of alkynesusing an air-stable and readily available manganese catalyst has been achieved. The reaction proceeds under mild reaction conditions and tolerates various functional groups, resulting in (Z)-alkenes and allylic alcohols in high yields. Mechanistic experiments suggest that the reaction proceeds via a bifunctional activation involving metal–ligand cooperativity
