    摘要: A process for resolving racemates of compounds of the formula I ##STR1## in which a, A, B, D, E, F, M, Q and R have the meanings given in the description is described. The process is carried in a manner known per se but using the optical antipodes of derivatives of phenoxypropionic acid.Also described are salts of deprenyl, ephedrine or tetrahydropapaverine with a phenoxypropionic acid of the formula ##STR2## in which U and T have the meaning stated in the description, and which result as intermediate in the racemate resolution.

    摘要: Bisimides of the formula I where R1, R2, R3 and R4 have the meanings stated in the description, are prepared in a process in which the corresponding dicarboxylic anhydrides of the formulae II and III R1—CO—O—CO—R2  (II) R3—CO—O—CO—R4  (III), are reacted with an amine of the formula H2N—R—NH2 in the presence of a tertiary amine.
