give 1,4- and 1,2-double addition products, and their subsequent transformations afforded multisubstituted pyrroles in good yields. Application of this procedure to the synthesis of an imidazole glycerol phosphate dehydratase inhibitor (IGPDI), a physiologically active 2,3,5-trisubstituted pyrrole, is also described.
