reaction of aryl substituted cyclopropyl nitriles with tosyl aldimines to give 2,3-diaryl-3-cyano-substituted pyrrolidines has been demonstrated. In all cases, the trans-diastereoisomer was determined to be the major product. The overall yield and diastereoselectivity of the reaction showed some sensitivity to the electronic and steric demands of the aryl cyclopropyl nitriles and the tosyl aldimines

Substituted-aryl cyclopropanecarbonitriles and derivative compounds are antidotes for thiocarbamate, triazine-type and acetamide herbicides. These antidote compounds are especially effective in safening thiocarbamate herbicides used to control grassy weeds in wheat.
