- To optimize key synthetic steps, including O-protection and Mitsunobu reactions, for efficient library generation.
Main Methods:
- Solid-phase synthesis utilizing resin-bound amines.
- Acylation with N-Fmoc-O-THP-hydroxyproline, followed by Fmoc deprotection.
- Reductive amination to form tertiary amine intermediates.
- Tetrahydropyranyl (THP) group deprotection and subsequent Mitsunobu reaction with phenols.
- Trifluoroacetic acid-mediated cleavage from the resin.
Main Results:
- Successful synthesis of a library containing 10,200 N-alkylated O-arylated hydroxyproline derivatives.
- Demonstrated the efficacy of optimized O-protection strategies and Mitsunobu reaction conditions for secondary alcohols.
- Established a robust solid-phase synthetic methodology for generating complex hydroxyproline-based compounds.
