Abstract: The invention relates to a method for producing bisimides of formula (I), wherein R , R , R and R have the meanings cited in the description. According to the inventive method, the corresponding dicarboxylic acid anhydride of formulas (II): R -CO-O-CO-R and (III): R -CO-O-CO-R are reacted with an amine of formula H2N-R-NH2 in the presence of a tertiary amine.

Abstract: Described is a method of resolving racemic mixtures of compounds of the formula (I) in which a, A, B, D, E, F, M, Q and R are as defined in the description. The method is carried out using prior art techniques but using the enantiomers of derivatives of phenoxypropionic acid. Also described are salts of deprenyl, ephedrin or tetrahydropapaverin with a derivative of phenoxypropionic acid of the formula (a) in which U and T are as defined in the description, such salts being formed as intermediates in the resolution of the racemic mixtures.
