METHOD FOR PRODUCING BISPYRROLIDINE COMPOUNDS

METHOD FOR PRODUCING BISPYRROLIDINE COMPOUNDS

The present application relates to a method for preparing compounds of the formula I in which, in a first step, γ-butyrolactone is reacted with diamines of the formula II to form bisamides of the formula Ill, with the amide function of the bisamides of the formula Ill then undergoing partial or comp...

Zusammenfassung:The present application relates to a method for preparing compounds of the formula I in which, in a first step, γ-butyrolactone is reacted with diamines of the formula II to form bisamides of the formula Ill, with the amide function of the bisamides of the formula Ill then undergoing partial or complete catalytic hydrogenation in step II) to form bispyrrolidine compounds of the formula I.
