- To create a resin with orthogonal loading sites for enhanced synthetic control.
Main Methods:
- Synthesis of a novel hydroxyl-functionalized cross-linker from 4-hydroxybenzaldehyde.
- Preparation of gel-type resins incorporating the cross-linker.
- Investigation of resin swelling properties.
- Demonstration of orthogonal reactivity at pendant and cross-linker sites.
Main Results:
- A facile two-step synthesis for the hydroxyl-functionalized cross-linker was achieved with high purity.
- The resulting regio-reactive resin (R3-resin) possesses distinct orthogonal loading sites.
