Rasta resin as support for TBD in base-catalyzed organic processes

► Novel polymer-supported catalyst for its use under solvent-free conditions. ► Rasta resin as a novel polymer support for a representative largely used strong base (TBD). ► Michael addition of dimethylmalonate and nitroalkanes to α,β-unsaturated ketones. ► Ring-opening of phenyl glycidyl ether. ► Tandem Michael-Henry reaction for the synthesis of a nitrochromene.
