【Abstract】 Aim To discuss in depth the synthesis of hydroxyethylene dipeptide-based β-secretase inhibitors; Methods Organic reactions such as nucleophilic addition and substitution assisted by organometallic agents, catalytic hydrogenation, and classic peptide coupling were used to synthesize peptidomimetic β-secretase inhibitors. Results Ideal reaction conditions and potential problems were investigated, and one of the designed β-secretase inhibitors 13 (as a model) was synthesized successfully; Conclusion This approach might be used to build up the β-secretase inhibitor library and to search for new molecular candidates.更多还原
