Abstract

Abstract Several N-substituted 3-hydroxy-4, 4-dimethyl-2-pyrrolidinone acrylate derivatives, selected to allow their attachment to a polymer, have been prepared and tested as dienophiles in the Diels− Alder reaction. The experiments, performed under TiCl 4 catalysis in solution or the solid phase with isoprene and cyclopentadiene as dienes, pointed out the difficulties associated with some of these compounds that failed to give the corresponding ...
