Nitrophenol resins for facile amide and sulfonamide library synthesis

Novel nitrophenol solid supports based on various resin materials (polystyrene, TentaGel, macroporous, PEGA, and silica gel) are reported for facile amide and sulfonamide library synthesis. The broad choice of resin materials available will allow the reaction to occur successfully in solvents ranging from nonpolar organic solvents to aqueous media.
