Acrylate and maleate functionalized resins were used to mask the nitrone moiety of a chiral pyrroline N-oxide to prevent the racemization at the C-3 stereogenic center and to link them to a solid phase. After the elaboration of the linked cycloadducts, the product was disconnected from the resin through a 1,3-dipolar cycloreversion/ intramolecular cycloaddition domino process.

Abstract
Acrylate and maleate functionalized resins were used to mask the nitrone moiety of a chiral pyrroline N-oxide to prevent the racemization at the C-3 stereogenic center and to link them to a solid phase. After the elaboration of the linked cycloadducts, the product was disconnected from the resin through a 1,3-dipolar cycloreversion/ intramolecular cycloaddition domino process.
