Abstract

Dialkylaminopyridines whose N-substituents bear a hydroxyl or amino group can be made economically from 4-cyanopyridine. Simple but selective alkylation of these compounds with commercial (chloromethyl) or (3-bromopropyl) polystyrene gives several new solid-phase catalysts which are highly active in promoting the acylation of hindered alcohols. Comparison of syntheses and reactivities, among these and some other heterocyclic polymers, illustrates several useful general principles of reactive polymer chemistry such as local concentration and microenvironment effects.
