development of synthetic methodologies where nucleophilicaddition reactions to imino carbons are utilized in crucial steps. This article summarizes double nucleophilicaddition reactions with alpha,beta-unsaturated aldimines, addition reactions using alkynyl imines, "umpoled" reactions of alpha-imino esters, and the use of iminium salts as reactive electrophiles.
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 imidazoleglycerolphosphatedehydrataseinhibitor (IGPDI), a physiologically active 2,3,5-trisubstituted pyrrole, is also described.
