A novel strategy for the synthesis of 3-sulfanylsubstituted 1-(arylamino)-pyrrolidine-2,5-dione derivatives via the alumina-catalyzed Michael addition of mercaptans to N-anilinomaleimides is described. The utilization of alumina in the synthesis offers important advantages such as good yields, conve

β¦ Synopsis
Polymer bound olefins undergo free radical initiated 1,2-addition when reacted with a variety of haloalkanes. The strategy could be applied successfully to the solid-phase synthesis of dihaloethenylcyclopropane carboxylic acids which are the key fragments of synthetic pyrethroids.
