Abstract

Octahydropyrrolo[3,pyrroles (V) are synthesized by 1,3-dipolar addition of maleic anhydride (II) to benzylidene amino acid esters (I) followed by opening of the anhydride fragment and recyclization. Compounds (V) inhibit enzymatic activity of thrombin. -(KUDRYAVTSEV*, K. V.; TROFIMOVA, E. V.; BORISOVA, A. O.; Russ. J. Org.
